Energy conversion exploration set B (plus)

Energy conversion exploration set B (plus) consists of :

Hand generator x 1

Solar cell with base x 1

Buzzer with base x 1

LED with base x 1

Motor fan with base x 1

Connecting wires x 2

The source of energy for this set is the light energy and kinetic energy. The solar cell converts light energy to electrical energy. The hand generator converts kinetic energy to electrical energy. The electrical energy will then be converted to light energy by the LED, kinetic energy by the motor and sound energy by the buzzer.
