if 40 watt bulb has higher resistance then a 100watt bulb
then according to joul farmula p=I^2R the 40 watt bulb more
power consume then 100 watt bulb.

Answer Posted / kiran

even if u take the resistance of 40 watt bulb higher than
100 watt bulb,as the current varies square(I^2) the power
consumption,so power consumed by 100 watt is higher than
former........

I have a small system with two motors that are running on 380 vac, 60 hz. These motors are expensive and I usally get them from Brazil. I am adding another motor to the system, but I want to purchase a 480 vac, 60 hz motor to use. It will be on a VFD that is rated fro 380 thru 480. Is this posible and will I have to use a larger motor and derate it?
