Question

which provides resistance in an electric circuit? wire light bulb battery switch

Explanation:

To determine which component provides resistance in an electric circuit, we analyze each option:

• A wire is typically designed to have very low resistance to allow current flow easily.
• A light bulb contains a filament that resists the flow of electric current, converting electrical energy into light and heat. This resistance is intentional for its function.
• A battery is a source of electrical energy (voltage) that provides the potential difference to drive current, not resistance.
• A switch is used to open or close the circuit, controlling the flow of current but not providing resistance.

Answer:

B. light bulb
