I WONDER - What Does A Resistor Do In A Circuit?

A resistor is a component that limits electric current flow in a circuit, similar to a speed bump slowing down cars. Resistors are used to control LED brightness and motor speed by converting electrical energy into heat. Resistance is measured in ohms, and different circuits require resistors with varying ohm values.

What unit is used to measure resistance, and why is it important?

Discuss the significance of different ohm values in circuits.
