We have already studiedhow does a rectifier workin our previous article and know that a rectifier diode allows the conduction of electric current only in one direction. This unique characteristic of allowing conduction in a specific direction also results in the rectification of electric current if ...
The primary function of a diode, including its role in rectification, regulation, and signal demodulation, highlights its versatility in electronics. Understanding what does a diode do in these contexts can greatly enhance one's grasp of electronic design. Understanding what is a diode involves looki...

A diode is an electronic component that directs the flow of electricity in one direction: Technical explanation of the working of diodes; Types and roles of diodes.
How Does an Inverter Work? To understand how an inverter works, imagine a bulb connected to abattery, creating a closed circuit that allows current to flow through the bulb. The bulb has two terminals that are ‘A’ and ‘B’. The positive and negative terminal of the battery is connected...
The input side of optoisolators could be a photoresistor, a photodiode, a phototransistor, a silicon-controlled rectifier or atriac. An optocoupled solid-state relay contains a photodiode optoisolator that drives a power switch on the output side, usually a complementary pair ofMOSFETs. ...
when there is a failed-open diode, the frequency ofVDC1VDC1will be the same as VAC1. With a functioning circuit, the ripples will occur at a frequency twice the input frequency. Using an oscilloscope, we can easily verify the operation of a diode bridge rectifier. If the frequency of th...
How does a Current Transformer Work? According to Faradays Ampere law, “If a magnetic field is integrated around a close loop of wire, the value of that integral is equal to the net current enclosed by the loop”. The primary winding of CT, the main loop has the wire with the current...
A diode is a one-way valve for electrons. A zener diode is also a one-way valve, but it also passes electrons in the other direction if they are above a certain voltage. The zener diode therefore turns a 10-volt sine wave into a clipped wave oscillating between 0 and 5 volts. This...
Diodes of most types can be tested in this way - power rectifier diodes, signal diodes, zener / voltage reference diodes, varactor diodes and many more forms of diode can all be tested.How to test a diode with a multimeterThe basic diode test is very simple to perform. Just two tests ...
