How a Transistor Switch Works

The transistor in Figure is used as a switch to turn the LED on and off. For example, a square wave

An ohmmeter can be used to check the state of a transistor i.e., whether the transistor is good or not.

There are three leads in a transistor viz. collector, emitter and base. When a transistor is to be connected in

1. What is a fuse? The fuse is an electric element protecting electric devices. It is commonly connected with a

In some cases, after isolating a fault to a particular circuit, it may be necessary to isolate the problem to a

Voltage Regulator The 78XX series of linear voltage regulators provide positive fixed output voltages for a range of values. The

A multimeter can be used as a fast and simple way to check a diode out of the circuit. A good

Clamp Meters using Current Transformer for AC Measurement Current transformer clamp meters are equipped with rigid jaws of made of

A digital multimeter is essentially a voltage-measuring tool with some current abilities. A clamp meter is basically a current-measuring tool

Accuracy: An instrument’s degree of veracity—how close its measurement comes to the actual or reference value of the signal being measured.
