JEE Main 2023 — Current Electricity Question with Solution

JEE Main 2023 (24 Jan Shift 1)

Question

As shown in the figure, a network of resistors is connected to a battery of 24 V with an internal resistance of 3 Ω. The currents through the resistors R4 and R5 are I4 and I5 respectively. The values of I4 and I5 are:

Show full solutionCorrect option: D
Correct answer
DI4=25 A and I5=85 A

Step-by-step explanation

Equivalent resistance of circuit
Req=3+2×22+2+2+20×520+5+2=12 Ω

Current through battery i=2412=2 A

Now, I4=R5R4+R5×2=520+5×2=25 A

and I5=i-I4=2-25=85 A
