When it is necessary to adjust the resistance value to control the current, the electric cylinder 8 is started to extend its piston rod to drive the upper electrode plate 3 to move in the vertical direction, so that the distance between the lower electrode plate 2 and the upper electrode plate 3 changes, thereby achieving the effect of adjusting the resistance value. Under the condition that the voltage remains unchanged, the effect of adjusting the current is achieved. Since the resistor generates heat after being energized, the aqueous solution inside the protective shell 1 The water in the liquid evaporates and the liquid level decreases, causing the float 41 to move downward, and then the deflection rod 42 deflects inside the inclined groove, causing the water blocking tray 43 to deflect upward along the arc groove 45 inside the water passing shell 44, thereby changing the relative position of the water blocking tray 43 and the water passing pipe 46, and injecting water into the water tank 48, and the water enters the water passing pipe 46 from the connecting pipe 47.
