What is the formula for 电Powerand电能Calculate器?

Core formula: P = V·I ｜ W = P·t ｜ 1 kWh = 3.6×10⁶ J. The tool returns results instantly using this formula and the selected parameters.

What engineering notes should I keep in mind when using 电Powerand电能Calculate器?

1 度电 = 1 kWh = 3.6×10⁶ J，是居民电费计量Company。交流电路中 P = V·I·cosφ，Apparent power S = V·I，Reactive power Q = V·I·sinφ。电费 = 电量(kWh) × unit price，不同时段峰谷Electricity price不同。
