Estimate current from power, voltage and power factor for DC and simplified single-phase AC loads.
Results are for information and preliminary estimation. For critical technical work, manufacturer data, local codes and qualified professional review take precedence.
For DC and simplified single-phase AC, I = P / (V × PF). Resistive loads are often close to PF=1; motors and electronic loads may differ.
Example: A 2300 W resistive load at 230 V draws about 10 A when PF=1.
Electrical and energy calculations are not final designs by themselves. Load profile, conductor conditions, protection, efficiency and local codes must be considered together. Sorsana tools are intended for preliminary sizing and scenario comparison.
Motor efficiency, starting current and power factor make real current different from a simple P/V calculation.
No. Cable size, installation method, ambient temperature, inrush current and local electrical codes also matter.
