A potentiometer is an electronic component that can adjust the resistance value. It is mainly used in scenarios such as volume control, brightness control, and signal attenuation, and is commonly found in electronic products such as audio equipment, walkie-talkies, and instruments.
Structural composition: It includes a black base, metal pins (for circuit connection), green insulating/fixing components, and a rotatable adjustment shaft (for changing resistance values).
Functional principle: By rotating the adjustment shaft, the contact position of the internal resistance sheet is changed, thereby continuously adjusting the resistance value and further controlling the current, voltage or signal strength in the circuit.
This type of potentiometer, with its compact structure and convenient adjustment, plays a key role in the parameter adjustment and functional control of electronic devices.
