In the circuit diagram given below, the current flowing across 5 ohm resistor is 1 amp. Find the current flowing through the other two resistors.

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
