Rheostats 30 Ohms- Nichrome Type, Bell Terminals

The Rheostat 30 Ohms - Nichrome Type with Bell Terminals is a laboratory variable resistor designed for adjusting current flow by varying resistance.

Key description:

It contains nichrome wire, which is a nickel-chromium alloy known for high resistance and heat tolerance, wound on an insulating cylindrical body.

The bell terminals include two terminals at the ends of the resistive wire and a third terminal on the slider rod for connection and ease of use.

By sliding the contact along the coil, continuous adjustment of resistance from near zero to 30 Ohms is possible.

The slider rod is metal, often chrome-plated for durability and smooth movement of the sliding contact over the coil.

The device is widely used in electrical experiments, educational labs, and testing environments where controlled current adjustment is required.

The construction ensures good electrical contact, thermal stability, and long life, making it reliable for variable resistance applications
