Question

The slope of the V-I curve is 60°. Calculate the value of resistance. Assume the relationship between voltage and current is a straight line.

(a) 1.732 Ω

(b) 1.608 Ω

(c) 1.543 Ω

(d) 1.648 Ω

I have been asked this question in an interview for job.

My doubt is from Dynamics in section Dynamics of Electrical Drives of Electric Drives

Answer 1

The correct option is (a) 1.732 Ω

Explanation: The slope of the V-I curve is resistance. The slope given is 60° so R=tan(60°)=1.732 Ω. The slope of the V-I curve is resistance.
