Our Amp Calculator simplifies electrical current (amperage) calculations for various circuits. Easily convert watts to amps, volts to amps, or find amps using Ohm's Law. Essential for electrical design, troubleshooting, and understanding power consumption in both AC and DC systems. Get precise results fast.
Formula:
Key Formulas for Amperage:
- Amps (I) = Watts (P) / (Volts (V) × Power Factor (PF))
- Amps (I) = Volts (V) / Ohms (R)
Where I is Current (Amps), P is Power (Watts), V is Voltage (Volts), R is Resistance (Ohms), and PF is Power Factor (for AC circuits, typically between 0.8 and 1, use 1 for DC or purely resistive AC).
