Experimentations with Kelvin's Bridge

Product Code : EL-ELE-13533

(Experimentation with Kelvin’s Bridge) is useful training product for measuring very small values of resistance, Kelvin’s double bridge or Kelvin’s bridge (as it is commonly known as) is a variation of wheatstone bridge and is based on the same principal. By setting the null point we can evaluate the unknown resistance.
