Description

An ammeter is an instrument used to measure the electric current in a circuit. It is typically connected in series with the circuit and provides a reading of the current flowing through it in amperes (A).

A square is a geometric shape with four equal sides and four right angles. In the context of a lab ammeter, “square” could refer to the shape of the ammeter’s display, which may be a square shape with a digital readout of the current measurement.
