If the two bulb rating is different(i.e 1st bulb 1000W,240V
& 2nd bulb 1000W,180V ) then the power consumed by each
bulb are
1st bulb KWH = 240 * 4.16 * h = (998.4 * h)KWh
2nd bulb KWH = 180 * 5.55 * h = (999 * h)KWh

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)
