Question

If two current phasors, having magnitude 5A and 10A intersect at an angle of 60 degrees, calculate the resultant current.

(a) 12.23 A

(b) 12.54 A

(c) 13.23 A

(d) 14.24 A

I got this question in a job interview.

Asked question is from Phasor Diagrams Drawn with RMS Values Instead of Maximum Values in portion Alternating Voltage and Current of Basic Electrical Engineering

Answer 1

Correct option is (c) 13.23 A

The explanation: Resultant current can be found using I^2 = I1^2 + I2^2 + 2I1I2 cosθ

Substituting the values, we get I=13.23 A.
