Electrical and Electronics Engineering Ohm’s law is a Basic Electrical and Electronics Engineering law which relates current, voltage and resistance in a circuit. Statement: The current in a resistive circuit is directly proportional to the applied voltage and inversely proportional to its resistance. Mathematical Formula, I = V/R Where I = Current in amps V = Voltage in volts … Read more
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 always connects in parallel to the line. A PT can be … Read more
