which provides resistance in an electric circuit?\no wire\no light bulb\no battery\no switch

Brief Explanations:

A light - bulb has a filament which offers resistance to the flow of electric current, converting electrical energy into light and heat. Wires are designed to have low resistance for efficient current flow. A battery provides electrical energy (emf) and a switch is used to open or close the circuit, not to provide resistance.

Answer:

light bulb
