Voltmeter

Detailed explanation-1: -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.
Detailed explanation-2: -An ampere (AM-pir), or amp, is the international unit used for measuring current. It expresses the quantity of electrons (sometimes called “electrical charge") flowing past a point in a circuit over a given time.
Detailed explanation-3: -The device used to measure current is ammeter. Hence, the correct answer is Option A. Note: There are two ways to measure electricity; one is by measuring current where ammeter is being used and another by measuring the voltage where voltmeter is being used.
