A) 1.5V
B) 1.0 V
C) 0.5 V
D) 3.2 V
Correct Answer: D
Solution :
Key Idea: In parallel resistances, potential difference across them is same. Potential difference across PM \[V=4\times 1=4\] volt (ie, across \[4\,\Omega \]) Equivalent resistance of lower side arm, \[{{\operatorname{R}}_{eq}}=1+\frac{0.5\times 0.5}{0.5+0.5}=1.25\Omega \] Now the circuit can be shown asYou need to login to perform this action.
