Difference between Electrical and Electronics

First of all, we know the definition of Electronics

What is Electronics

Electronics is the branch of science that deals with devices and circuits that operate by controlling the flow of electrons and other electrical charge particles. Here we see the word controlling, the word controlling of electrons is very important in electronics and electronic devices because in electrical devices there is no control of electrons. we can control the flow of electrons in electronics.

What are Electronic devices?

 Electronic devices are those devices that perform a particular task by controlling the flow of electrons. For example, a normal electronic device is a diode. here a diode is designed to perform the task of as a switch in forward, In reverse bias, a diode performs a task as an open switch by controlling the flow of electrons.

Electronic devices are devices that utilize electronic circuits and components to perform various functions. These devices are designed to manipulate electrical currents or electromagnetic fields to generate, transmit, receive, or process information, as well as to control other devices or systems.

Electronic devices can range from small handheld gadgets to large-scale industrial equipment. They are commonly powered by electricity and typically consist of several components such as integrated circuits (ICs), transistors, resistors, capacitors, diodes, and other electronic elements. These components work together to perform specific tasks or functions.

Examples of electronic devices

  1. Smartphones and tablets: These portable devices combine various features such as communication, computing, and multimedia capabilities.
  2. Computers and laptops: These devices are used for data processing, storage, and running applications.
  3. Televisions and monitors: These devices display visual content using electronic circuits to generate images.
  4. Cameras: Digital cameras capture and store images or videos using electronic sensors.

Following are more differences according to different parameters 

Material-In Electronics We use mostly semiconductor materials like silicon and germanium. Materials used are mostly highly conductive like Aluminium, Copper, and silver in electrical devices.

Operating principle– we use electrical energy to perform a particular task. It works on Low voltage. Convert A form of energy into another form of energy to perform a particular task.

Current-Mostly uses Direct Current (DC) in Electronics devices. We use alternating current in electrical devices for performing a particular task.

Voltage – Electronic devices work on low voltage. Electrical devices work on High voltage.

Power consumption– In Electronics devices There is low power consumption. In Electrical devices, there is high power consumption.

What are Electrical devices?

Electrical devices are those devices that perform tasks Only the flow of electrons, or we can say that electrical devices are those devices that will change one form of energy in another form of energy.

Electrical devices are devices that operate using electricity as a source of power. Unlike electronic devices, which primarily manipulate electronic currents or electromagnetic fields, electrical devices generally focus on the generation, distribution, control, and utilization of electrical energy.

Electrical devices typically consist of components that facilitate the flow of electricity, such as wires, switches, fuses, transformers, and motors. These devices may also include electronic components for control or monitoring purposes, but their primary function revolves around the management of electrical power.

Examples of electrical devices 

  1. Lighting fixtures: Devices such as lamps, light bulbs, and fluorescent tubes that produce light when an electric current passes through them.
  2. Heating appliances: Devices like electric stoves, electric heaters, and electric water heaters that convert electrical energy into heat.
  3. Power outlets and switches: These devices provide access to electrical power and control the flow of electricity in a building or structure.
  4. Electrical motors: Devices that convert electrical energy into mechanical energy, used in various applications like electric fans, pumps, and electric vehicles.
  5. Transformers: Electrical devices that transfer electrical energy between different voltage levels, commonly used in power distribution networks.
  6. Circuit breakers and fuses: Safety devices that protect electrical circuits from excessive currents and prevent damage or fires.
  7. Generators: Devices that convert mechanical energy into electrical energy, often used as backup power sources or in remote locations.
  8. Power supply units (PSUs): Devices that convert alternating current (AC) to direct current (DC) and provide regulated electrical power to electronic devices.
  9. Electric meters: Devices used to measure and monitor electrical consumption in residential, commercial, and industrial settings.
  10. Electrical wiring and cables: These components are used to connect electrical devices and transmit electricity within a building or structure.

Response time – The response time of Electronic devices are slow with the comparison of electrical devices.

Required space– Electronic devices required less space than electrical devices.

Safety– Electronic devices are safer than electrical devices.

Uses – Basically most of the mechanical type work is operated in electrical devices. In Electronic devices, We can use it for coding or decoding of information or for amplifying a weak signal.

We see here what are differences and comparisons with different parameters between Electronic and Electrical devices. We read and study electronics and electrical but generally, we don’t have knowledge about the differences between them because we never think about this.

Similarities between electronic and electrical devices

While there are distinct differences between electronic and electrical devices, there are also some similarities between the two:

  1. Power source: Both electronic and electrical devices require a power source to operate. They rely on electrical energy, typically provided through a power outlet, battery, or other power supply.
  2. Circuits: Both types of devices utilize circuits to control and direct the flow of electricity. Electronic devices contain electronic circuits, which consist of components such as transistors, capacitors, and resistors. Electrical devices contain electrical circuits, which may include switches, fuses, and wiring.
  3. Components: Electronic and electrical devices often share common components such as wires, connectors, and power sources like batteries or power supplies. While electronic devices incorporate additional specialized electronic components, both types of devices rely on fundamental electrical components like resistors, capacitors, and transformers.
  4. Interconnections: Electronic and electrical devices can be interconnected to form complex systems. For example, electronic devices may rely on electrical wiring and outlets for power supply, and electrical devices may utilize electronic control circuits for automation or regulation.
  5. Integration: Modern devices often combine both electronic and electrical elements. Electronic components are integrated into electrical devices to provide control, automation, or additional functionality. This integration allows for enhanced performance, energy efficiency, and user interaction.
  6. Safety considerations: Both electronic and electrical devices require proper safety measures. Electrical devices may incorporate safety features like fuses and circuit breakers to prevent electrical hazards, while electronic devices may have built-in protection circuits to safeguard sensitive electronic components.
  7. Application overlap: In some cases, the line between electronic and electrical devices can blur as they serve overlapping purposes. For example, devices like smartphones or laptops contain both electronic components (processors, memory, etc.) and electrical components (power supplies, connectors, etc.).
  • Both devices work on the flow of electrons.
  • The transformer is the primary device in both electronic and electrical devices. Because Mostly an electronic device get DC power from AC power by the reduce the required level of voltage and current using a step-down transformer, and after through a rectifier converting AC to DC. (Step-down and Step-up transformer only works with AC power).
