Question 499: Current Electricity

Question

In the given electrical network, the value of resistance ' $R$ ' when the current in the galvanometer will be zero, is

Accepted Answer

The potential difference across resistance $R$ is 6 V . Hence, current, $\mathrm{i}=\frac{10-6}{4}=\frac{4}{4}=1 \mathrm{~A}$ Thus, $1 	imes \mathrm{R}=6$
$$ \mathrm{R}=6 \Omega $$
