DC electric power
Use voltage and current calculate electrical power and energy.
Your numbers
Power for physics
Ideal SI-unit model for learning. Real components, tolerances, losses and safe operating limits need separate checking.
Compare scenarios
You fit keep up to three snapshots for this tab. Loading one go replace the present inputs.
Formula
Use P = VI and E = Pt/1000. V na voltage for V, I na current for A, and t na operating hours. Power P dey for W and consumed energy E dey for kWh.
Use voltage and current calculate electrical power and energy.

- Electric current (A)
- 2
- How long equipment run (hours)
- 5
- Power for physics
- 24 W
- Energy wey equipment use
- 0.12 kWh
Where e fit work and limits
Ideal SI-unit model for learning. Real components, tolerances, losses and safe operating limits need separate checking.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
