The current '' in the circuit shown in the figure is 
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
In the given question, Resistance in series with 2ε is not given, assuming it to be R.The above circuit can be redrawn as,Using equivalent battery for the dotted portion shown in the figure below,εeq=εR+2εR1R+1R=1.5ε and Req=R2. Therefore,i=3-1.5ε2.5+0.5R=ε2R
