Concept explainers

Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.

Hi, I have a question regarding electromagnetism. The question is as follows: An aluminum rod has a resistance of 1.590 Ω at 20.0°C. Calculate the resistance of the rod at 102°C by accounting for the changes in both the resistivity and the dimensions of the rod. The coefficient of linear expansion for aluminum is 24.0 ✕ 10-6 (°C)−1.
