Answer / subhash sharma
P= root 3 V I Cos fi. and I=P/root 3*V*Cos fi
is common formula rather motor is running in delta or
star.formula remains same.where:
P= Motor capacity in watt
V=Applied voltage across stator
I=current drawn in amp
Cos fi= power factor.

Answer / mohd saaim
pls find the formula
P=eta root3VI cosfie
I=p/eta root3V cosfie
where p= power of motor
eta= efficiency
V= voltage
I=current
cosfie= power factor

Answer / thowsif
Pls find the formula
P=Root3*V*I*P.f
I=P/Root3*V*P.f.
"P" is Capacity of the 3 Phase IM.

Answer / parthiban
p=root3 vi cospie
p=power in motor
root3= three phase
v=voltage
i=current cospie= pover factor
