Which one of the following electrical meter has the smallest resistance?

Which one of the following electrical meter has the smallest resistance?

Options

(a) Ammeter
(b) Milliammeter
(c) Galvanometer
(d) Voltmeter

Correct Answer:

Ammeter

Explanation:

A milliammeter will have greater resistance than ammeter because,

1. Number of turns in the coil in milliammeter is increased to compensate low value of current to create large deflection.

2. Milliammeter does not have usually a shunt in parallel because main current is very small. Ammeter usually have a shunt in parallel which makes overall resistance low.
