Hi,
Thanks. I am planning to learn LTspice.
The Falstad circuit is working fine. I just use the interface to draw the circuit to give a snapshot here. However, I tried the same circuit on a solderless prototype board. The circuit in simulator (Falstad) is working fine. However, in reality, it is not.
Moreover, I tried to avoid the bias resistors (to the gate of the mosfet) with the same result (I tried this since, the mosfet datasheet says that it's gate can handle +/- 20v and giving a gate voltage of 10v means that the operating region will change - in this case the Drain source can allow more current).
I am doubting on the Multimeter probes which I am using to measure the current since when I short the probes in ohmmeter mode, the reading sways between 0.3 to 0.6.
I think I have to use the current sensor like the ACS712 model and measure the voltage at its output. By that method, I think we can get a more accurate current right? Because, as per the datasheet of that current sensor IC, it outputs few millivolts for every ampere. But I doubt whether the multimeter can measure such a small voltage.
Thanks
