Resistance & Resistors

Resistance makes it harder for current to flow.

Let’s understand the idea with water first, then see what a resistor does in an electrical circuit.

Resistance restricts flow

See how a restriction changes how easily flow can move.

Water example
A water pipe restriction reducing how easily water can flow through the pipe.

A restriction makes it harder for water to move through a pipe.

The water can still flow, but the restriction reduces how easily it can pass.
