Answer 2

Explanation:

Answers. The Unit Of Current is defined as the flow of 1 coulomb of charge in one second . Its unit is Ampere.

Ammeter (Ampermeter) Measures current

Capacitance meter Measures the capacitance of a component

Current clamp Measures current without physical connection

Curve tracer Applies swept signals to a device and allows display of the response

Voltmeter

(a) Voltmeter is the device used for measuring potential differences. Voltmeter is always connected in parallel to the resistance. (b) Generally the resistance of Voltmeter is higher than the resistances which we will use.As they are in parallel the voltage across them is equal.
