Question

Find the value of the currents I1 and I2.

(a) 0.3, 0.1

(b) -0.1, -0.3

(c) -0.3, -0.1

(d) 0.1, 0.2

The question was asked in an interview for internship.

I would like to ask this question from Kirchhoff’s Voltage Law in division Simple DC Networks of Basic Electrical Engineering

Answer 1

Correct choice is (d) 0.1, 0.2

To explain: Using KVL in loop 1, 10-100 i1=0. i1=0.1A

Using KVL in outer loop, -100i2+20=0  i2=0.2A.
