Physics - Current Electricity Question with Solution | TestHub

The circuit can be redrawn asSo, the circuit is break in two parts. As the other end of $8\Omega$ resistor is grounded, is at zero potential, the potential difference across $8\Omega$ resistor $=24-0=24\mathrm{V}$ So, current in $8\Omega$ resistor $\mathrm{I}=\frac{\mathrm{V}}{\mathrm{R}}=\frac{24-0}{8}=3\mathrm{A}$.
