Question

What will be the ammeter reading if the bulb has a resistance of 0.5 ohms​

Answer 1

Explanation:

The voltage remains the same across the circuit as it is a parallel connection. So, the current across the upper half of the circuit where the ammeter is connected is calculated as I = V/R = 12.04 (total voltage)/12(Resistance R1) = 1 A. Hence, the ammeter will read 1 A.
