Question 524: Current Electricity

Question

The current drawn from the battery in the given network is (Internal resistance of the battery is negligible)

Accepted Answer

The given circuit can be drawn as:
From the figure, we can see that this is a balanced Wheatstone bridge.
$$\begin{array}{ll}
	herefore & \frac{1}{R}=\frac{1}{10}+\frac{1}{10}=\frac{2}{10}=\frac{1}{5} \
	herefore & R=5 \Omega \
	herefore & I=\frac{12}{5}=2.4 \mathrm{~A}
\end{array}$$
