Electric power (P = VI)
Power consumption as the product of voltage and current. The SI unit is W (watt), but kW is common for household appliances and hp / PS (horsepower) for vehicles.

数式
P = V × I
変数
| P | electric power (W) |
|---|---|
| V | voltage (V) |
| I | electric current (A) |
計算例
電圧 V = 100 V、電流 I = 5 A の電気ストーブの消費電力を求めよ。
P = V I
P = 100 \times 5
P = 500\,\mathrm{W}
