Ohm's Law Verification
V = I × R
0 = 0 × 0
P = V × I
0 = 0 × 0
P = I² × R
0 = 0² × 0
Circuit Building Guide
Getting Started
1. Drag components from the palette onto the circuit board
2. Click and drag between connection points to create wires
3. Complete the circuit and observe real-time measurements
Ohm's Law
V = I × R
Voltage equals Current times Resistance
Power Formulas:
P = V × I = I² × R = V² ÷ R
Meter Connections
Ammeter: Connect in series with the circuit
Voltmeter: Connect in parallel across components
