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? WebMar 24, 2014 · Here's a little known fact: The human body, at any given moment, produces energy equivalent to a 100 watt light bulb. In that sense, we're always wasting our …
