Question 219 of 380

In the given circuit the cells have zero internal resistance. The currents (in amperes) passing through resistance ${R}_{1}$ and ${R}_{2}$ respectively, are:

A$0,1$B$2,2$C$0.5,0$D$1,2$

Show answer and solution▾

Answer: (C) $0.5,0$

Assume ${V}_{F}$ as $0$

$as {V}_{E}={V}_{B}$

$\Rightarrow$ Current in ${R}_{2}$ is zero

${V}_{A}-{V}_{D}=10V$

$\Rightarrow I=\dfrac{10}{20}=\dfrac{1}{2}A$ from $A$ to $D$
