The meaning of the fuse resistor is to divide the voltage and limit the current. Generally, it is connected in series with the load (electrical appliance) to prevent the load (electrical appliance) from burning out and forming a short circuit. Also the role of insurance. I don't know if my explanation is clear or not, my language skills are poor

  The fuse is blown, and it needs to be replaced. The fuse resistor will not break, mainly to prevent short circuits in the circuit (short circuits are too dangerous and may cause fires, etc.). As for the resistance value of the fuse resistor, it depends on the actual problem. If it is too large, it will waste a lot of power on the resistor.
