Ohm's Law Calculator — Formel
## Ohm's Law
Ohm's law is the foundational relationship in circuit analysis, connecting voltage, current, and resistance.
### Formula
**V = I * R**
where V is voltage in volts, I is current in amperes, and R is resistance in ohms. Power dissipated is P = I² * R.

where V is voltage in volts, I is current in amperes, and R is resistance in ohms. Power dissipated is P = I² * R.
Lösungsbeispiel
2 amperes flowing through a 10 ohm resistor.
- V = I * R
- V = 2 * 10
- V = 20 V
- P = I² * R = 4 * 10 = 40 W
