Hello,
In attachment below, the amp meter reads 4.78ma.
I always figured that when R2 would drop to 20 ohms, the current would increase. But it simply stays the same!!!
Why??
Wouldn't lowering the resistance allow more current through the circuit??
In other words, the current is always 4.78ma weather 51 or 20 ohms is connected! So I wouldn't even know why I would need any R2 resistor there..... except for the odd situation where the mosfet would allow its channel to fully open hence R2 would be there for security purpose....!!!!
So my question is, why does the IR2 always stay the same no matter what resistor we use?
Thanks all for your replies!
