A potentiometer uses a movable contact on a resistive element to provide a documented adjustable divider or resistance.

## What it represents

A potentiometer uses a movable contact on a resistive element to provide a documented adjustable divider or resistance. Its end terminals and wiper must be distinguishable.

## How to read it

- Trace the wiper separately from the two fixed ends.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

## Information to show or reference

- State resistance value
- Identify wiper and ends
- Reference intended adjustment range

## Important distinction

A potentiometer used as a divider has three circuit connections; a rheostat connection uses a variable resistive path.

## Facts

- Drawing role: Passive circuit element
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HVR1R4, VVR1R4 (Autodesk identifiers; not IEC symbol numbers)
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
