The resistor parallel circuit is the most basic parallel circuit. All responsible circuits can be converted into resistor series circuits and resistor parallel circuits to understand the working princ

In a 24V system, I use PMOS as a switch, and occasionally the PMOS will be damaged.
I originally thought it was an accident, but later found out it was a design problem.
This is the circuit diagram of
