Find the value of IL if IC=10A and IR=6A.(a) 4A(b) 18A(c) 12A(d) 2AThe question was posed to me in an interview.I'm obligated to ask this question of Simple Parallel Circuits in chapter Single-Phase Parallel Networks of Basic Electrical Engineering

Answer»

Correct choice is (a) 4A

To explain I would say: I is the TOTAL current in the circuit. Since this is a parallel CONNECTION, the total current in the circuit is equal to the sum of the CURRENTS in each branch of the circuit. HENCE I=IC+IR.

10=IC+6=>IC=4A.
