Problems solved by technology

[0003] At present, there are related records about variable resistors. For example, the patent with the publication number CN204558172U discloses a solid variable resistor, which changes the resistance value of the resistor manually, and has low frequency, poor periodicity and no continuity. ; The patent application number is 201510166498.3 discloses a motor-driven sliding variable resistor, the resistor changes the resistance value through the way the motor drives the slide plate, but the resistance substrate used in this patent is linear, if If you want the output to be an alternating resistance, you need to drive the motor back and forth, which causes the motor to run back and forth at a very low frequency, otherwise the motor will have a large inertia force and be easily damaged

Description

technical field [0001] The invention belongs to the technical field of electronic components, and in particular relates to a sinusoidal waveform alternating resistor. Background technique [0002] At present, there are devices capable of outputting alternating voltage and alternating current in electrical components, but up to now, there is no device capable of generating alternating resistance. In various large-scale event venues that require regular adjustment of sound intensity and light brightness, alternating resistors are one of the necessary devices. Alternating resistance, as the name implies, is a device that can produce a resistance value that changes periodically with time. This device has important scientific and technological value in the study of physical and electrical issues. [0003] At present, there are related records about variable resistors. For example, the patent with the publication number CN204558172U discloses a solid variable resistor, which chan...
