Experimentation with Kelvin’s Bridge 

Experimentation with Kelvin’s Bridge is a useful training product for measuring very small values of resistance. Kelvin’s double bridge or Kelvin’s bridge (as it is commonly known) is a variation of Wheatstone bridge and is based on the same principle. By setting the null point we can evaluate the unknown resistance. This product has Digital Display (DPM) for the purpose of null detection implemented on the trainer board itself.

FEATURES:-

• Easy illustration of Kelvin’s bridge
• Digital display (DPM) for null detection
• In-built sine wave generator
• Adjustable frequency and Amplitude of Sine Wave
• Digital display for Null detection

SCOPE OF LEARNING:-

• Determination of unknown resistance using Kelvin’sbridge method
