Resistance

Resistance determines how easily electric current flows through materials. High resistance hinders current flow, while low resistance facilitates it. Conductors have low resistance, whereas insulators have high resistance. Resistance is crucial in circuits, affecting how components like light bulbs and heating elements function. Ohm's Law explains the relationship between voltage, current, and resistance. Resistance is measured in ohms and can cause heat loss, especially in long wires, but also provides safety by preventing electric shocks. Insulators like rubber gloves protect against electrical hazards.
