How to calculate single phase apparent power
This calculator finds single-phase apparent power by multiplying voltage by current.
How the calculation works
Apparent power = Voltage × Current.
Example
120V at 15A: 120×15 = 1,800 VA.
Frequently asked questions

Pro Tips for Single Phase Apparent Power
- Apparent power (VA) differs from real power (watts) when power factor is less than 1 — multiply apparent power by power factor to get real power.
- This calculates apparent power specifically, useful for sizing circuits and transformers, which must handle apparent power regardless of power factor.
Common Single Phase Apparent Power Mistakes to Avoid
- Confusing apparent power (VA) with real power (watts), which are the same only when power factor equals 1 (a purely resistive load).
