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

in india why 50 hz and 220 volt taken as standard rating for equipments whereas in US 100hz and 110v is consided as standard rating.is this method save power.
