Trimmer potentiometers

Potentiometer

Potentiometer is an electronic element that is used to control and regulate electrical devices, as changing the electrical resistance can change the output electrical voltage. A potentiometer is a passive element consisting of a sliding contact, a resistor, a contact, and an actuator, which is a knob or lever that rotates or a slider that moves. It is used, for example, in audio systems to control the volume of the sound produced by the audio equipment. It works as a voltage divider.

Trimmer potentiometers

Trimmer potentiometers are potentiometers with terminals for soldering, the characteristic of which is that they have a variable capacity of the resistance. These are linear or logarithmic adjustable electronic potentiometers, simple with a screw that can be adjusted with a screwdriver.

Linear and logarithmic

Linear potentiometers are controls that move in uniform, staggered steps, meaning that when the rotary knob is in the middle of the scale it is assumed to be 50% or half of the maximum on the dial. With logarithmic potentiometers, the adjustment of moves in uneven steps that progress to a certain degree and grow along the length of the dial. This means that when the pointer of the potentiometer has reached the middle of the scale it may mean that it is using 25 or 30% of the maximum possible force.
