Question 1 • LHS Physical Science

Which provides resistance in an electric circuit?

Answer
A
wire
B
light bulb
C
battery
D
switch

Explanation

A light bulb provides resistance in a circuit as electric current passes through its filament. The filament resists the flow of charge and converts electrical energy into light and heat. A wire is designed to offer very little resistance, while the battery supplies energy and the switch opens or closes the circuit.
