The formula to calculate power in kilowatts (kW) is:
\[ P(kW) = \frac{I(A) \cdot V(V) \cdot PF}{1000} \]
Where:
Let's say the current (\( I \)) is 10 amps, the voltage (\( V \)) is 230 volts, and the power factor (\( PF \)) is 0.8. Using the formula:
\[ P(kW) = \frac{10 \cdot 230 \cdot 0.8}{1000} \]
We get:
\[ P(kW) = \frac{1840}{1000} = 1.84 \]
So, the power (\( P \)) is 1.84 kW.
The conversion from amps to kilowatts (kW) involves multiplying the current (in amps) by the voltage (in volts) and the power factor (for AC circuits), then dividing by 1000. This calculation is useful for determining the power consumption of electrical devices.
