Concepts

Components of a Circuit: Exploring the role of a potentiometer as a variable resistor that can
control the flow of electricity.

Importance of Energy Management: Discussing how controlling fan speed can lead to energy
conservation in homes and industries..

Hands-on Experience: Students will develop practical skills in using electronic components and
making real-time adjustments to a circuit.

Observations

Students will learn how a potentiometer functions as a variable resistor. They will observe how
turning the knob changes the resistance in the circuit, affecting the fan speed. To connect the
potentiometer to the fan and power source. They will gain hands-on experience with basic circuit
components and wiring.

Applications

1. Motor is used in electronic appliances such as
blender, fan, etc.

2. In car toys motor is widely used to changes the
speed and for controlling.
