Answer / jai prakash narain singh

for same capacity of motor,incase it runs in star it will
draw more current reason being,phase voltage=line voltage
divided by root of 3.where as power remains same.
as you know,power =root of 3 xvolt x current xcosine angle
of volt and current, since power remains same and voltage
has reduced in this case current will increased. if this
motor is connected in delta,and suppose its full load
current is I amp,
and in star current will be root of 3 x I AMP.
