WebApr 4, 2024 · Definition : – A current transformer ( CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. These transformers with low range ampere meters are used to measure the current in the high voltage circuits.
WebOld-style incandescent light bulbs force current to flow through filaments so thin that light is generated. That is, volts = amps x ohms. R stands for resistance in this formula. If resistance is unknown, the formula can be converted to R = E/I (ohms = volts divided by amps).
