Ohm's Law Verification
Graphical Verification using Ammeter & Voltmeter
Explore Ohm's Law (V = IR) by adjusting the resistance and observing the current and voltage measurements. The graph will plot voltage against current to show the linear relationship.
Resistance: 10Ω
0.00A
0.00V
Adjust Resistance (Ω)
Observation:
Adjust the resistance slider to see how it affects current and voltage according to Ohm's Law (V = IR).
The Science Behind Ohm's Law
Key Concepts:
Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points:
- V = I × R where:
- V = Voltage (Volts)
- I = Current (Amperes)
- R = Resistance (Ohms)
Graphical Verification:
When you plot voltage (V) against current (I), you should get a straight line passing through the origin. The slope of this line gives the resistance (R).
Circuit Components:
In this experiment:
- Ammeter measures current (connected in series)
- Voltmeter measures voltage (connected in parallel)
- Resistor provides resistance in the circuit
