Darkness detector Shadow alarm circuit

Darkness detector Shadow alarm circuit

Light sensor circuit Shadow detector A Buzzer beeped and led will glow for a fixed time when a shadow falls on a phototransistor. This is a very sensitive light-sensitive circuit operated using the 741 opamp ic and 555 timers. Here 741 ic is connected as a comparator which compares the voltage at the input. It is able to detect the […]

What is Comparator

What is Comparator

Comparator A comparator is a circuit that compares two input voltages or currents and gives output High or Low as per input signal. The Output is a digital form according to the input signal compared with the reference. Basically a comparator is used in electronics to compare the two Analog input signals given on both input terminals and we get […]

Ohm’s Law

Ohm’s Law

Ohm Law What is ohm’s law In the electrical field, Ohm’s law is a very important topic. This law is asked in almost all interviews and as basic fundamentals of electrical engineering for all who related to electrical engineering. This is a very important fundamental law that describes the Relation between Current, Voltage, and Resistance. There are three main quantities […]

Operational amplifier (Op-amp)

Operational amplifier (Op-amp)

Operational Amplifier (op-amp) An operational amplifier or op-amp is basically a multistage, very high gain amplifier having very high input impedance (typically a few Mega ohms) and low output impedance(Less than 100 ohms) and has the capability to amplifying signals of frequency ranging from zero HZ to 1MZ. Opamp is basically a multistage, direct-coupled, negative feedback amplifier that uses voltage […]
