A circuit contains an ammeter, a battery of 30 V and a resistance 40.8 ohm all connected in series . If the ammeter has coil of 480 ohm and a shunt of 20 ohm, the reading in the ammeter will be

In the circuit shown in figure-3.388, each ammeter has coil resistance 2 Omega , find reading of the two ammeters.

A resistance box, a battery and a galvanometer of resistance G ohm are connected in series. the galvanometer is shunted by resistance of S ohm, find the change in resistance in the be required to maintain the current from the battery unchanged.

(A) : An ammeter is connected in series in the circuit. (R) : An ammeter is a high resistance galvanometer.

(A) : An ammeter is connected in series in the circuit. (R) : An ammeter is a high resistance galvanometer.

In the above question, if the internal resistance of the battery is 1 ohm , then what is the reading of ammeter

A simple circuit contains a 12 V battery and a bulb having 24 ohm resistance. When you turn on the switch, the ammeter connected in the circuit would read
