Multi-turn Potentiometer Pacco-PM


[Product Description]

In-line type multi-turn potentiometer equipped with a built-in variable resistor mounted on a transparent plastic body (a rotary type potentiometer). Achieved easier connection with an electric circuit compared to conventional sliding/wire-wound type resistors.

[Overall Advantages to Users]

Connectable to electric parts/components in a circuit in two ways thanks to its body structure which is equipped with mechanisms shown below that significantly increase students’ efficiency in completing circuits successfully.

  • Built-in leads with clips (red & black): the potentiometer can be easily connected to terminals of other products.

  • Built-in terminals on both sides of the body:  leads with clips (red & black) of other electric parts/components can be easily connected to the potentiometer.


  • Variable resistor
  • Ohm’s law
  • Electromotive force and Internal resistance of a battery
  • Simple electric circuit

[To teachers]

  • Shorter time required for preparation and experiment compared with a conventional sliding resistor because the potentiometer can be directly connected into an electric circuit.
  • Potentiometer helps students understand difficult concepts derived from Ohm’s law like an electromotive force and internal resistance of a battery.

[To students]

  • Easy to find the relationship between resistance, voltage, and current in a circuit summed up in Ohm’s law.
  • Easy to complete an electric circuit by using the potentiometer thanks to its compact and lightweight body compared with a sliding resistor.
  • Designed to increase efficiency in completing circuits for a student by intuitively and correctly selecting one of the two optional mechanisms.
