Electricity Converter | How to use and interpret results
Solve a resistive electrical model from two of voltage, current, resistance and power. A separate prefix-unit mode helps with quantities, but does not add AC circuit modelling.

How to use this tool
In Ohm's-law mode fill exactly two independent quantities in V, A, Ω or W. In unit mode, choose units of the same physical quantity rather than mixing voltage and power.
Results and examples
12 V and 2 A imply 6 Ω and 24 W using V=IR and P=VI. These ideal-model values do not by themselves determine safe component ratings.
Worked example
12 V and 2 A imply 6 Ω and 24 W using V=IR and P=VI. These ideal-model values do not by themselves determine safe component ratings.
Limitations
- AC phase, power factor and three-phase power are not modelled.
- Wiring rules and overcurrent protection are not checked.

Frequently asked questions
What power corresponds to 12 V and 2 A?
12 V and 2 A imply 6 Ω and 24 W using V=IR and P=VI. These ideal-model values do not by themselves determine safe component ratings.
Can I apply this directly to an AC motor?
AC phase, power factor and three-phase power are not modelled. Wiring rules and overcurrent protection are not checked.
