Question

In 3phase current i know the voltage & watts how to find out amp

Answer 1

watts / voltage = amps

Answer 2

You cannot.

The relationship between power (watts) and the current involves power factor. P=V X I X pf.

If you have an idea of the load you may be able to estimate the power factor but that's as good as it gets.

Answer 3

Current,I in 3-phase =Watts/V(1.732)

Answer 4

in a 3 phase system the relationship is

P(watts) = I ( Amps) x E (Volts) x sqrt of 3 or 1.732

to solve for amps

I= P/E x sqrt 3

there ya go from the E....
