Resistance and Ohm`s Law Notes
... Resistance is the opposition to charge movement. As electrons move through a material, they constantly collide with atoms in the material and with other electrons. These collisions cause some of the energy carried by the charge to be released as heat. Symbol: Resistance is a function of several fact ...
