Question

What is the purpose of making internal resistance of milli-ammeter very low?A) High accuracy.B) Minimum voltage drop across meter.C) Maximum voltage drop across meter.D) High sensitivity.

Answer 1

B) Minimum voltage drop across meter

Step-by-step explanation:

An ammeter is a measuring instrument device that is used to measure small currents flowing through a circuit in milli-ampere. The internal resistance of the milli ammeter is very low so that there would be a minimum voltage drop across the meter causing a minimum effect of the current in the circuit, this results to a measurement closer to the original value. If a high resistance is place, there would be large voltage drop therefore the current measured would be lesser than the original value.
