Answer :

Given I= 1 A (Across 5 ohm)

R= 5 ohm


The potential drop across AB, V = I × R


or V= 5 ohm × 1A = 5V


In a parallel circuit, the potential difference across the ends of all resistors remains the same. Therefore the potential difference across 4 ohm and 10 ohm will be 5 V


The current flowing through the 4 ohm resistance


= V/R = 5/4 = 1.25 A


Current through 10 ohm resistor = V/R = 5/10 = 0.5 A
