A LITTLE CONTEXT
How to use electrical power calculator
- Enter or edit the example values in the input panel.
- Review the method below and choose the options that match your task.
- Run the tool, check the result, and copy or download it. Reset restores the example; Clear removes your input and result.
Method & assumptions
P = VI for DC electrical power.
This is a DC model using voltage and current magnitudes. AC real power additionally requires power factor and phase information and is not calculated here.
Result units: DC power (W)
Worked example
- Voltage magnitude (V)
- 12
- Current magnitude (A)
- 2
