Can friction power a light bulb
WebLight does not experience friction. Friction is a phenomenon we observe when two materials (composed of matter) slide past one another. Light is a form of energy and … WebViewed 11k times. 1. I'm studying a lightbulb and its variable resistance, given by the expression: R ( T) = R o [ 1 + α ( T − T 0)], where R 0 is the resistance of the lamp at T 0. In this case, R is not given by Ohm's law ( V = R i ). So, which expression can I use to calculate the power consumed by a lightbulb?
