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