The net resistance of an ammeter should be small to ensure that

$\begin{array}{1 1}(A) \text{It does not get overheated} \\ (B)\text{ It draws sufficient current from the circuit necessary for its functioning}\\ (C) \text{It can measure large current} \\ (D) \text{It does not appreciably change the current to be measured} \end{array}$

1 Answer
