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

0.5 A

2 A

4 A

5 A

Explanation:

It is given that emf of the battery, E = 12V
Resistance of the bulb, R = 24 W
where switch is turned on, current through the bulb is I=E/R = 12/24= 0.5A
Hence, reading of ammeter is 0.5 A.
