The circuit shown in the figure contains three resistors R1 =100Ω, R2 = 50Ω, and R3 = 50Ω and cells of emf’s E1 = 2V and E2. The ammeter indicates a current of 50mA. Determine the current (mA) in the resistor R2 :


Correct answer is '20'. Can you explain this answer?
Verified Answer
The circuit shown in the figure contains three resistors R1 =100&Omega...


Applying KVL in loop ABCD

E1 = (I + 0.05) R1 + IR2

I = –20mA

Current through R1 = 30mA towards right

Current through R2 = 20mA towards left

Applying KVL in loop BGFE

E2 = (I + 0.05) 100 + (0.05) 20 = 4 volts




The correct answer is: 20
