Matrices EAMCET – Part 1

Here are some of the most important points from matrices to be understood and remembered by EAMCET aspirants. Product of two upper triangular matrices is a upper triangular matrix. Determinant of triangular matrix is the product of the elements in the principle diagonal. (i) trace (KA) = K tr(A)(ii) tr (A + B) = tr(A) …

Measuring Low Resistance Using Kelvin Double Bridge

We aim to measure the resistance of a given resistor using Kelvin Double Bridge and determine its tolerance. Kelvin Double Bridge is nothing but a modification of Wheatstone bridge. It is used for measuring of low resistance to a good precision. It compares two ratio arms P,Q and p,q and hence is called ‘double bridge’. …
