📖 About This Experiment
Ohm's Law is a fundamental principle in electrical engineering that describes the relationship between voltage, current, and resistance in an electrical circuit. This experiment visualizes electron flow through a simple circuit with adjustable voltage and resistance.
💡 Key Concepts
- •Voltage (V): Electrical potential difference, measured in Volts
- •Current (I): Flow of electric charge, measured in Amperes
- •Resistance (R): Opposition to current flow, measured in Ohms (Ω)
- •Power (P): Rate of energy transfer, measured in Watts
- •Electron Flow: Moves from negative to positive terminal
🔢 Key Formulas
Ohm's Law
V = I × R
I = V / R | R = V / I
Power Law
P = V × I
P = I²R | P = V²/R
Electrical Energy
E = P × t = V × I × t
