The aluminum housing resistance is the same as other resistors.
The resistance (Resistance is usually indicated by "R"), and the aluminum housing resistance indicates the magnitude of the conductor's effect on the current blocking in physics.
The greater the resistance of the conductor, the greater the resistance of the conductor to the current.
he resistance of the same kind also has the resistance of the heating body; the different conductors, the resistance is usually different, the resistance is a characteristic of the conductor itself.
The resistance will cause the change in the amount of electronic circulation, the smaller the resistance, the greater the amount of electronic circulation, and vice versa.
