Here's a breakdown:
* Current: The flow of electrical charge through a material.
* Resistance: The opposition to this flow of charge.
The higher the resistance, the more the material impedes the flow of current. Resistance is measured in ohms (Ω).
Factors Affecting Resistance:
* Material: Different materials have different resistances. For example, copper has low resistance (good conductor), while rubber has high resistance (good insulator).
* Length: Longer materials have higher resistance.
* Cross-sectional Area: Thicker materials have lower resistance.
* Temperature: For most materials, resistance increases with temperature.
