Hi himani!
1- I have started getting pulses, don't know how.. And the pulses vary when the load changes i.e. they increase with an increase in the load and decrease when load decreases. The pulses stop when no load is connected. So the pulse problem is solved. I still wonder how it automatically got solved.
2- Currently I don't have a reference meter to compare the results of my circuit. Beside this I don't have a voltage source that can provide voltages in range of +-30V for V2 and +-165mV for V1. I vary V1 by the use of potentiometer (VR1 470k TRIM-POT) as can be seen in the circuit diagram.
3- I am measuring V1 and V2 by a multimeter, by setting the knob of multimeter to Vac in milivolt range. Currently I don't have arrangements for checking the phase difference between input voltage and current.
4- I have changed the load as you suggested. Now i have arranged 4 100W bulbs as load. And new calculations were still very different.
5- I turned on only a 100Watt bulb for 60 seconds, to check the number of pulses and i was getting around 44 pulses. but according to the following formula, which gives the number of pulses per minute, I should have got only 5.33 pulses.
P= X x100x60 / 1000x3600 here X=3200 (meter constant)
Can you please tell what could be possibly wrong with my circuit? I am making this as my Final Year Project and have only a month left to submit it..
