Question
A potentiometer is connected between A and B and the balance point is obtained at 203, 6cm When the end of the potentiometer connected to B is shifted to C, then the balance point is obtained at 24.6 cm. If now the potentiometer be connected between B and C the balance point will be at
Options
A.179.0 cm
B.197.2 cm
C.212.0 cm
D.228.0 cm
Solution
e1 = 203.6 ....... (i)
e1 - e2 = 24.6 ....... (ii)
(i) - (ii) give e2 = 179.0cm
e1 - e2 = 24.6 ....... (ii)
(i) - (ii) give e2 = 179.0cm
