Legge di Ohm.
Ricava tensione, corrente, resistenza e potenza da due valori.
Direct current relationship V = I × R. Power = V × I. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
- Voltage
- 10 V
- Current
- 2 A
- Resistance
- 5 Ω
- Power
- 20 W
Voltage = current × resistance. Power = voltage × current.

Direct current relationship V = I × R. Power = V × I. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
Find voltage, current, resistance and power from any two electrical values. Direct current relationship V = I × R. Power = V × I. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
2 A through 5 Ω gives 10 V and 20 W.
