Given:
1 amp current is flowing through 5ohm resistor.
We know that in case of parallel connection, the p.d. across each resistor is same and is equal to the voltage applied.
Therefore, applied voltage, V = IR = 1 × 5 = 5V
So,
Current through 4 ohm resistor = $\frac{\text{V}}{\text{R}}=\frac{5}{4}=1.25\text{A}$
Current through 10 ohm resistor = $\frac{\text{V}}{\text{R}}=\frac{5}{10}=0.5\text{A}$
