Definition

Resistance is the property of a material that opposes the flow of electricity. It is measured in ohms.

The higher the resistance of a material, the more difficult it is for electricity to flow through it. For example, copper has a low resistance, so electricity flows through it easily. Rubber has a high resistance, so electricity does not flow through it easily.

Resistance is important in electrical circuits. It is used to control the flow of electricity and to protect circuits from damage.
