Physics - Current Electricity Question with Solution | TestHub

Two $4\Omega$ resistors are in parallel combination. Their equivalent resistance $$=\frac{4\times 4}{4+4}=\frac{16}{8}=2\Omega$$
$\therefore$ Total resistance of the network $=2+1=$ $3\Omega$ $\therefore$ Current through $1\Omega$ resistor $=\frac{6}{3}=2\mathrm{A}$
