Description for WOODEN METER BRIDGE (with pencil jockey)
A meter Bridge with a pencil jockey is a physics lab apparatus for determining the relative resistance of a cable element. This is made of 1-meter wood, copper plate, and pencil jockey.
The ends gaps are closed by removable Copper Binding pieces which are held in position by the terminals.
The 24 SWG constantan wire is stretched along the top of wooden meter scale and securely clamped to the Brass end strips so that end errors are negligible.
The four-gap bridge has a large and heavy copper strip of mounted on a heavy 3/4-inch-thick laminated base.
Nine heavy Brass terminals lock type are provided to reduce the resistance to a minimum.
Supplied complete with pencil jockey along with lead for connections.
- A meter bridge is a tool used in electrical engineering and physics labs to measure the resistance of a conductor or a circuit.
- The meter bridge consists of a long, straight wire, which is divided into two unequal parts, and a galvanometer.
- A jockey or a sliding contact is used to move along the wire until the galvanometer shows zero deflection.
- The jockey used in a meter bridge is a thin, pointed rod or wire, usually made of brass or steel, mounted on a wooden handle.
- The position of the jockey is noted, and the resistance of the unknown resistor is calculated using a formula.
