Question

Two identical batteries, each with emf 18 V and internal resistance 1 ohm, are connected in parallel. This combination is connected across a 4 ohm resistor. The current in the 4 ohm resistor is:
Options
A 1.0 A
B 2.0 A
C 4.0 A
Correct Answer
D 3.6 A
Correct Answer

Option C is the correct answer.

Detailed Explanation

Parallel identical cells: emf stays 18V, r_total = 0.5 ohm. I = 18/4.5 = 4.0 A.

Hint

Parallel identical cells: emf stays 18V, r_total = 0.5 ohm.
