R1 to R6 is 470 ohm
Vdd is 20v
the arrow is connected to gate of PMOS, PMOS is sharing the same Vdd 20v
may i ask, why is there no resistor on the base of NPN ? if theres one, what is it used for ?
what is the purpose of R1 to R6 resistor?
sorry, my electronics is really horrible, i hope you can clear my doubt
