Answer 2

Answer:

$\mathscr{\huge{\pink{HELLO}}}$

$\huge\red{\ddot\smile}$

A method of finding the internal resistance of a cell when the value is known to be high. A second cell, a galvanometer and a resistance are connected in series with the cell under test, and the value of the resistance required to give a galvanometer. deflection of half the value obtained with the cell alone is found.
