Question

Should the resistance of an ammeter be low or high? Give reason. ​

Answer 1

Answer:

The resistance of an ammeter should be low. An ammeter has to be connected in series with the circuit to measure current. In case, its resistance is not very low, its inclusion in the circuit will reduce the current to be measured. In fact, an ideal ammeter is one which has zero resistance.
