Question 574: 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 redrawn as shown in the figure. It is a balanced Wheatstone bridge. No current will flow through $$5 \Omega$$ resistance, and hence it can be removed from the circuit. $$3 \Omega$$ and $$2 \Omega$$ resistances are in series. Hence we have two branches with $$5 \Omega$$ resistances each, connected in parallel. Their equivalent resistance is $$2.5 \Omega$$
$$	herefore \quad \mathrm{I}=\frac{\mathrm{V}}{\mathrm{R}}=\frac{6}{2.5}=2.4 \mathrm{~A}$$
