Ohms law 3 phase

[liquidtite]

I forgot how to find Amps for 3phase is it p/e x .732 ?
thanks

Close. But take care what you mean by your variables. "e" I understand to be voltage. But your "p" could mean either apparent power (VA) or real power (watts). The constant of interest os not ".732," but rather "1.732": the square root of 3. The forumulas are,

• Current = VA / (voltage times 1.732)
• Current = Watts / (power factor times voltage times 1.732)

I forgot how to find Amps for 3phase is it (p/e) / 1.732 ?
thanks

edit to add: Following charlie's post,

pretty close

Apply some algebra to P = E x I x 1.732
