Zener Diode Voltage Regulators

Zener Diodes can be used to produce a stabilised voltage output with low ripple under varying load current conditions. By

In studying the various electronic, electrical networks and systems, signals which are functions of time, are often encountered. Such signals

An individual transistor can be tested either in-circuit or out-of-circuit with a transistor tester. For example, let’s say that an amplifier

The IEC also defines how manufacturers should mark the values of resistors and capacitors in the standard called IEC 60062.

Several faults that can occur in the circuit and the accompanying symptoms are illustrated in Below Figure. Symptoms are shown

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
