Marie-Dolores bought a hand crank flashlight just in case the power goes out. When she turns the handle very fast, the light goes on. In this case, cranking the handle is mechanical energy. The mechanical energy creates magnetic and electrical energy.

Question

This type of flashlight contains everything needed to create an electrical current that transforms electrical energy into light. However, it does NOT have one common component of a circuit. What is not needed for a flashlight like this?
Responses
A wireswires
B conductive metalconductive metal
C a complete circuita complete circuit
D an initially charged battery

Answer 1

The correct answer is D. an initially charged battery.

In a hand crank flashlight, the mechanical energy generated by cranking the handle is directly converted into electrical energy, which powers the light. This type of flashlight does not require a pre-charged battery to work, as it generates its own electrical current through the mechanical action.
