In a potentiometer circuit, a cell of EMF 1.5 V gives balance point at 36 cm length of wire. If another cell of EMF 2.5 V replaces the first cell, then at what length of the wire, the balance point occurs?
(1) 60 cm
(2) 21.6 cm
(3) 64 cm
(4) 62 cm Continue reading In a potentiometer circuit, a cell of EMF 1.5 V ….

Infinite Grid of Resistors
|
There is an infinite wire grid with square cells. The resistance of each wire between neighbouring joint connections is R. Find the equivalent resistance of the whole grid between points x and y. |
