Concept explainers

Temperature Variance of Resistance

Electrical resistance or simply resistance is the property of a material that opposes the free flow of electrons through it. The total amount of resistance to the flow of charges (or current) is affected by many factors like the length of the conducting material, its cross-sectional area, resistivity, and temperature.

Question

A light bulb has resistance of R = 150 Ω and has a current of I = 1.1 A passing through it.

Express the power P using the variables I and R.
