Formula used
I = P / (V x pf)Explanation of each input
- Power (W) โ the power used in the calculation.
- Voltage (V) โ the voltage used in the calculation.
- Power factor โ the power factor used in the calculation.
Understanding your result
- Current โ the calculated current in A.
Step-by-step calculation
For the example values 1000W, 230V:
- Apply the formula:
I = P / (V x pf) - Substitute the values: 1000/230
- Result: about 4.35 A
