Explanation:
Detailed explanation-1: -A moving coil galvanometer is an instrument which is used to measure electric currents. It is a sensitive electromagnetic device which can measure low currents even of the order of a few microamperes.
Detailed explanation-2: -Instruments such as digital multimeters, current probes, and clamp meters are often used to measure current.
Detailed explanation-3: -An ammeter (abbreviation of Ampere meter) is an instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. For direct measurement, the ammeter is connected in series with the circuit in which the current is to be measured.
