Building and Testing a Simple Circuit

Objective

Create a simple electrical circuit to understand the concepts of voltage, current, and resistance.

Materials

• Battery
• Wires
• Light bulb or LED
• Switch (optional)
• Multimeter
• Notebook for recording data

Instructions

1. Set up a simple circuit by connecting the battery, light bulb, and wires.
2. Measure the voltage across the battery and the current through the circuit using a multimeter.
3. Record the measurements in your notebook.
4. Experiment with different resistances by adding or removing components and measuring the changes in voltage and current.
5. Analyze your findings to understand the relationship between voltage, current, and resistance (Ohm’s Law).
6. Present your results in a report, explaining the principles of electrical circuits and their applications.
