Which of the following bulbs will have high resistance?

(a) 220V, 60W

(b) 220V,100W

(c) 115V,60W

(d) 115V,100 W

This question was posed to me during a job interview.

My doubt is from Ohm’s Law topic in chapter Circuit Elements and Kirchhoff’s Laws of Network Theory

The correct choice is (a) 220V, 60W

Easiest explanation: Resistance is directly proportional to square of voltage and inversely proportional to the power.
