Current Divider Rule Example # 3: To Find the Unknown Resistor Using CDR

Statement: Two resistors R1 (500 ohms) and R2 (unknown) are connected in the parallel configuration. The current across R1 is known to be 5 A. Whereas the current entering the circuit is 30 A. Apply the current divider principle to find the current flowing the unknown resistor.

Solution: By applying the formula:
