Question:
In the given circuit the cells have zero internal resistance. The currents (in Amperes) passing through resistance $R_{1}$ and $R_{2}$ respectively, are:
Correct Option: , 3
Solution:
(3) Current passing through resistance $\mathrm{R}_{1}$,
$\mathrm{i}_{1}=\frac{\mathrm{v}}{\mathrm{R}_{1}}=\frac{10}{20}=0.5 \mathrm{~A}$ and, $\mathrm{i}_{2}=0$
