Can friction power a light bulb

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? WebResistance of a light bulb Let's use the power equation to calculate the resistance of a 100 W light bulb. The bulb's power is 100 W when the potential difference is 120 V, so we can find the resistance from: 2 2 22120 144 100 V PIR R R V R P ⎛⎞∆ ==⎜⎟ ⎝⎠ ∆
