Definition of a Current Probe A current probe is an electrical device that measures and quantifies the number of amperes that flow or pass through a conductor. Also known as a current clamp or a current meter, the instrument finds application in computing the alternating current (AC) operating in a conducting device. It also assesses and determines the waveform and phase. A … [Read more...] about What is the Working Principle of a Coreless Clamp-on Current Probe?
