Using a solar panel as a source of electrical energy, make a circuit to run a toy fan.
To make a circuit using a solar panel to run a toy fan, proper connections must be made between the components.
(1) Connect the positive terminal (red wire) of the solar panel to one terminal of the toy fan motor. (2) Connect the negative terminal (black wire) of the solar panel to the other terminal of the fan motor.
(3) Place the solar panel in direct sunlight. (4) The solar panel converts sunlight into electrical energy, which flows through the circuit and powers the fan motor, causing the fan blades to rotate.
Expected outcome: When the solar panel receives adequate sunlight, it generates electrical energy that powers the fan. The fan will rotate as long as sufficient sunlight falls on the solar panel. If the sunlight is blocked or reduced, the fan will slow down or stop.
Explanation
The chapter mentions on page 2 that 'electricity is generated in multiple ways—by windmills, by using wind energy, by solar panels capturing the Sun's energy, by falling water and by using natural gas or coal.' A solar panel acts as a source of electrical energy similar to a cell or battery. The circuit principles remain the same—a complete path must be formed for current to flow from the positive terminal, through the motor, and back to the negative terminal.
Solution Steps
Connect the positive terminal (red wire) of the solar panel to one terminal of the toy fan motor
Connect the negative terminal (black wire) of the solar panel to the other terminal of the fan motor
Place the solar panel in direct sunlight
