What does a clip-on ammeter measure?

A clip-on ammeter is specifically designed to measure the current flowing through a conductor without direct electrical contact. It operates based on the principle of magnetism: when current flows through a conductor, it creates a magnetic field around it. The clip-on ammeter detects this magnetic field and translates it into a measurement of the current.

While the strength of the magnetic field is related to the measurement process, the primary purpose of the clip-on ammeter is to provide an accurate readout of the current in amperes. This capability makes it a valuable tool for electricians and technicians who need to assess electrical systems easily and quickly.
