Whether or not the P channel MOSFET conducts in the schematic diagram above depends on the polarity of the power source across the circuit.

  • Connecting the gate directly to ground turns  P channel enhancement mode MOSFET on. Usually the Source is more positive than the drain, but it is OK that it isn’t in this circuit.
  • P channel enhancement mode MOSFET connected to positive supply turns the transistor off. That is the normal way to wire a P channel enhancement mode MOSFET so that it is off.
