K6-32: POTENTIOMETER

Additional Info

  • ID Code: K6-32
  • Purpose: Find an unknown EMF using a voltage divider.
  • Description: A battery of voltage V is connected across a resistive wire of length L. A second, "unknown" lesser voltage battery is connected through a meter to the slide tap of the potentiometer. Find the distance L1 along the wire where the clip lead draws no current. The unknown voltage Vu is then: Vu=V L1/L External batteries can be used to provide a different battery configuration if desired.
  • Availability: Available
