Ohm's Law Verification
V = I × R Experiment
This interactive experiment demonstrates Ohm's Law by measuring voltage and current across different resistors. Change the resistor value and observe how it affects the current while voltage remains constant.

Ohm's Law Demonstration
What's Happening:
When you complete the circuit:
- Voltage (V) is provided by the battery (9V in this case)
- Current (I) flows through the circuit
- Resistance (R) opposes the current flow
- The relationship between them follows Ohm's Law: V = I × R
Key Observations:
- With constant voltage, increasing resistance decreases current
- The current is inversely proportional to the resistance
- The voltage remains constant (9V) throughout the experiment
- This verifies Ohm's Law (V = IR) as the calculated values match the measured ones
Real World Applications:
- Designing electronic circuits with appropriate resistors
- Calculating power consumption in electrical devices
- Troubleshooting electrical circuits
- Understanding how devices limit current flow
