MCQs, Transformer
A transformer is an electrical device which steps the ac voltages from one level to another. Being one of most important device in Electrical and Electronics Engineering various exams, jobs interviews, college tests, include transformers. Given below is the list of...
Transformer
A current transformer is an instrumentation transformer which steps down the AC current to a safe level (usually 1 Amps or 5 Amps full scale) so that relays and measurement devices can easily deal with current. Our electrical power system carries heavy currents of...
Transformer
The potential transformer is an instrumentation transformer which steps down the AC voltage to safe level of 120 V or 240 V so that relays and instrumentation devices can sense. The potential transformer is usually referred to as a step-down or voltage transformer. It...
