Find the value of IR if I=10A and IC=8A.(a) 5A(b) 18A(c) 12A(d) 2AI got this question during an interview for a job.My doubt is from Simple Parallel Circuits in chapter Single-Phase Parallel Networks of Basic Electrical Engineering

Answer»

Right answer is (d) 2A

Easy EXPLANATION: 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=8+IR=>IR=2A.
