Answer / andrew d&

I/VxR
where I = CURRENT, v = VOLTAGE and R = resistance.

Answer / thanigaivel

p=v*icos@
i=p/v
p=power-watts
v=voltage-volts
i=current-amps
cos@-power factor

Answer / raj

If We want to calculate the current of a circuit we should know at last two factors. The basic formula from OHM's law is

I= V/R
and also I= W/V
in 1phase power factor is neglected but in three phase it should be consider
