Two bulbs, one of 600W and the other of 100W having same
voltage rating are connected in series across the supply in a
room.Which bulb will glow brighter? If one of the bulb is
switched off, what will be effect on illumination?
Answer Posted / pradeep kumar
100 watts would glow
brighter..! Because both the
bulbs were connected in
series..
So current flowing through
both would be equal..
Power output(brightness)=
I^2*R..
The bulb with high power
rating has less resistance..
So 100watts bulb has high
resistance.. So 100 watts
bulb's power output would
be higher..!!

I just want to convert the voltage into current i.e. suppose I have 750V & 1A AC power then I want to convert it into 12V & 62A DC power only difficulty is that I don't want to use the tranceformer. Simply to say, I want to make the step-down without using tranceformer. Please, give me some ideas. And also I want the relation between Magnetic Induction & Weight of the body can be levitated. Or I can say, how much of magnetic induction requires to lift 500gms weight? I am heartily thankful to you.
