The Electrical Resistance of Conductors

Electrical resistance in conductors is a measure of how much a material opposes the flow of electric current. Think of it like friction for electricity—materials with high resistance, like rubber, slow down the current, while metals with low resistance, like copper, allow electricity to pass easily. Resistance depends on the material’s properties, its temperature, and its size (thicker or longer wires affect resistance). Lower resistance means more efficient flow of electricity, which is essential for transmitting power and making electrical devices work effectively.
