Question

which device provides electrical energy to run an electric circuit?
○ the wire
○ the switch
○ the battery
○ the light bulb

Explanation:

• The wire is used to conduct electric current, not to provide electrical energy.
• The switch is used to open or close the circuit, controlling the flow of current, not providing energy.
• The battery is a source of electrical energy; it converts chemical energy into electrical energy to power the circuit.
• The light bulb is a load in the circuit that converts electrical energy into light and heat, not a source of energy.

Answer:

C. the battery (assuming the options are labeled A, B, C, D with A: the wire, B: the switch, C: the battery, D: the light bulb)
