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 / baljinder singh
According to I=V/R. The resistance of 40W bulb is high than
100W bulb , but current flowing in it low rather than 100W
bulb. The Power= I^2R. The current is multiply with own
first ,because it has square ,and then it multiply with
voltage. So when current is decrease the power is consume by
bulb is less..

I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
