In a metre bridge [Fig. 3.27], the balance point is found to be at 39.5 cm from the end 4, when the resistor Y is of 12.5 Q. Determine the resistance of X. Why are the connections between resistors in a Wheatstone or meter bridge made of thick copper strips? Determine the balance point of the bridge above if X and Y are interchanged. What happens if the galvanometer and cell are interchanged at the balance point of the bridge? Would the galvanometer show any current?
