Transistors and thyristors are semiconductors switching devices. They are used for controlling current flow in circuits. They play a very important role in all power conversion devices. In this article…
The difference between kVA and kVAR is pretty simple. "kVA" is the unit of apparent power whereas "kVAR" is the unit of reactive power. Before getting into the topic, we…
Several operating indications can be seen on the front of an ACB or MCCB. Being an electrician or an engineer it is important that one must understand those indication and…
PIV stands for 'Peak Inverse Voltage'. It refers to the maximum reverse bias voltage a semiconductor diode or other semiconductor devices can withstand without damaging themselves. The peak inverse voltage…
When we speak about DC electricity, resistance is the term used to refer to opposition to current flow whereas impedance is the term used in AC electricity. Impedance is basically…
