Losses in a DC Generator

Efficiency is a very important specification of any type of electrical machine. When we talk about efficiency, losses comes into

A transformer is an extended version of an inductor. The flux that is created inside the inductor is used here

Transformers reduce the voltage of the electricity supplied by the utility to a level suitable for use by the electric

Duty cycle basics Duty cycle is the ratio of time a load or circuit is ON to the time a

Continuity Testing using Multimeter Turn the dial to Continuity Test mode ( ). It will likely share a spot on

1. Turn the dial to ṽ. Some digital multimeters (DMMs) also include m ṽ . If voltage in the circuit

If your digital multimeter offers a frequency setting (Hz is the symbol) on the dial: Turn the dial to Hz.

A multimeter determines capacitance by charging a capacitor with a known current, measuring the resulting voltage, then calculating the capacitance.

How to test diodes Digital multimeters can test diodes using one of two methods: Diode Test mode: almost always the

Electric motor is a machine which converts electric energy into mechanical energy. Its action is based on the principle that
