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.

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.

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:

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.

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).
