Find the total current if IC=2A and IR=5A.(a) 3A(b) -3A(c) 7A(d) 10AThe question was posed to me in an interview.I would like to ask this question from Simple Parallel Circuits in portion Single-Phase Parallel Networks of Basic Electrical Engineering

Answer»

Right answer is (c) 7A

To explain: 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.

I=2+5=7A.
