What is resistance? Discover how it impedes electrical flow, and why understanding it can help us to build more effective circuits, and stay safe.Key facts
- Resistance is how well or poorly an electric current flows through an object.
- Conductors have low resistance and insulators have high resistance.
- Resistance is measured in ohms.
- Resistance can protect us from electric shocks.

Resistance in an electrical circuit creates both problems and opportunities.
Resistance
Resistance is how well, or how poorly, an electric current flows through an object, like a wire or a light bulb.
The higher the resistance, the harder it is for the electric current to flow through it.
The lower the resistance, the ...
