Photocell Experiment (To Study the Variation in Photoelectric Current with Intensity of Light)

Overview:
This project demonstrates the principle of the photoelectric effect by studying the variation in photocurrent with the intensity of light. The experiment is set up on a cardboard base and uses a solar panel, LED light source, and banana sockets to connect a multimeter for measurement. It provides a hands-on approach to understanding how light intensity affects the generation of electric current in a photovoltaic cell.

Components Used:

1. Cardboard Base: A lightweight and portable platform to mount all components.
2. Solar Panel: Acts as the photocell, converting light energy into electrical energy.
3. LED: A controlled light source for illuminating the solar panel.
4. Banana Sockets: Convenient terminals to connect a multimeter for measuring photocurrent.
5. Multimeter (not included): Used to record the current generated by the solar panel.
6. Wires and Connectors: For setting up the circuit and ensuring proper connectivity.

Working Principle:

1. When the LED light source illuminates the solar panel, it generates an electric current due to the photoelectric effect.
2. The intensity of the light is varied (by adjusting the distance of the LED or using a dimmer circuit).
3. The generated current is measured using a multimeter connected via the banana sockets.
4. Observations are recorded, showing how the photocurrent changes with varying light intensity.
