How to Use the Watts to Amps Calculator

Power plus voltage or resistance — same pattern again, working backward from power this time instead of forward to it.

Using voltage:    I = P ÷ V
Using resistance: I = √(P ÷ R)

The voltage route is the direct power-formula rearrangement; the resistance route takes a square root, since power scales with the square of current (P = I²R) rather than current directly. This Watts to Amps Calculator handles whichever value you're starting from.
