Photo Cell Selenium type mounted in the box.

The Photo Cell Selenium type mounted in the box is a laboratory apparatus consisting of a selenium photo cell securely enclosed within a metal or plastic box. The device is designed with a transparent window or aperture that allows light to reach the selenium cell, which converts light energy into electrical energy based on the photoelectric effect.

Key Features

Construction: Selenium photo cell mounted on a metal base inside a protective enclosure, with electrical connections brought out at terminals for easy interfacing.

Accessories: Often supplied with a lamp holder for a 60-watt bulb to provide a controlled light source for experiments.

Measurement: The apparatus typically includes analog or digital meters for measuring current and voltage output from the photo cell, useful for studying the photoelectric effect and light intensity.

Dimensions: The box is compact, typically around 300 mm x 175 mm x 75 mm, making it suitable for laboratory benches.

Applications: Used to demonstrate and verify principles like the inverse square law of light intensity, photocurrent generation, and characteristics of photo cells in physics laboratories.

Usage

Ideal for educational demonstrations in physics and electronics teaching labs.

Helps visualize and understand the relationship between light intensity and electrical output.

Enables practical study of selenium photo cells and their behavior under varying light conditions.

This selenium photo cell mounted in a box provides a safe, convenient, and effective way to explore photoelectric phenomena in laboratory settings, facilitating accurate measurement and reproducible experimentation.
