Electric current is measured by which instrument? A. Voltmeter B. Ammeter C. Barometer D. Sinometer

The correct answer is B. Ammeter.

An ammeter is an instrument used to measure electric current in a circuit. It is connected in series with the circuit, and the current flowing through the ammeter is proportional to the deflection of the needle on the ammeter’s scale.

A voltmeter is an instrument used to measure electric potential difference, also known as voltage. It is connected in parallel with the circuit, and the voltage across the voltmeter is proportional to the reading on the voltmeter’s
