Embodiment 1
[0034] Implementation example 1, such as Figure 1-2 As shown, a linear controllable resistor with increasing resistance is characterized in that it includes an insulating container G11, a conductive liquid G31, an entity G21, a bottom electrode G51, an upper electrode R50, a resistance layer R51, an electromagnetic coil G41, and a controlled The first node O+ of the path, the second node O- of the controlled path, the first node P+ of the control end, and the second node P- of the control end;
[0035] The insulating container G11 has a stable shape. The shape of the insulating container G11 is cylindrical, and the container of the insulating container G11 is cylindrical.
[0036] The conductive liquid G31 is contained in the cavity of the insulating container G11, the volume of the conductive liquid G31 is smaller than the volume of the insulating container G11, and the volume of the conductive liquid G31 is larger than half of the volume of the insulating container G11;

Embodiment 2
[0046] Implementation Example 2: A modification is made on the basis of implementation example 1, so that a tilt switch K1 is connected in series between the bottom electrode G51 and the second node O- of the controlled channel to prevent the resistor from being used when it is placed incorrectly.
Embodiment 3
