Potentiometer

A potentiometer is a manually adjustable variable Resistor with 3 terminals.

How can the resistance be changed so easily??

  • You move a wiper across a resistive strip (carbon ring)
  • oohhh i get it

Only two pins are used: one outside pin and the center pin.

The longer the path of resistance, the higher the resistance. Outside doesn’t change.

  • Only right and center pins are used in the diagram
