A 50 Hz overhead line has line to earth capacitance of 1.2 uf .It is decided to use an grounded fault neutralize determine the reaction to neutralize the capacitance of ? 1 100% of length of line 2 90 % of the length of line 3 80% of length of line
Let us first understand the term Pythagorean triplet and then we will use a formula to determine all the numbers in a Pythagorean triplet of the given options one by one. First, we will divide the given number by two, then we will use n2−1
is also said that glass rod attracts the small uncharged paper pieces when it is becomes positively charged. I understand that a positively charged glass rod attracts the uncharged pieces of paper because some of the electrons present in the paper accumulate at the end near the rod, but can't we extend the same argument on attraction of negatively charged silk rod and the pieces of paper due to accumulation of positive charge near the end?
Because, when they are rubbed together, the teflon rod gains the electrons from the cloth. Which means that the cloth will lose its electrons. Thus, the combined net charge of both the objects will remain the same. This is the Law of Conservation of charge.
