The Pencil Jockey is a physics laboratory accessory used as a sliding contact for potentiometer and Wheatstone Bridge experiments. It is designed for school physics labs, college practical rooms, STEM classrooms, and teacher-led electricity experiments where students need controlled contact with a resistance wire.
Product Description
The Pencil Jockey by School Equipments is used to make temporary electrical contact with a potentiometer wire or bridge wire during practical experiments. The verified related jockey design includes a moulded ribbed insulating handle, plated-brass contact with locating notch, plated-brass terminal, and 4mm socket.
This accessory supports experiments where students locate a balance point, compare potential differences, determine unknown resistance, or work with a Wheatstone Bridge arrangement. The live related School Equipments jockey page confirms dimensions of 95mm x 15mm; confirm whether the same dimensions apply to the final Pencil Jockey listing before publication.

How to Use the Pencil Jockey
- Connect the Pencil Jockey to the circuit using a compatible 4mm plug lead.
- Place the contact tip gently on the potentiometer or bridge wire.
- Slide the jockey along the wire without pressing heavily.
- Observe the connected galvanometer or meter for null deflection or balance condition.
- Mark or record the wire length at the balance point.
- Lift the jockey before changing circuit connections.
- Repeat readings carefully to improve experimental reliability.
Safety note: use only low-voltage laboratory circuits, avoid scraping the resistance wire, and never press the contact hard enough to damage the wire scale.
Care & Maintenance
- Keep the contact point clean and free from corrosion.
- Store the jockey in a dry box after use.
- Do not bend or file the contact tip unless maintenance is approved.
- Check the 4mm socket and contact alignment before each practical session.
