In a meter bridge the balance point is found to be at `39.5` cm from the end A, when the resistor Y is of `12.5 Omega`. Determine the resistance of x. why are the connections between resistors in a wheat stone or meter bridge made of thick copper strips?
What happens if the galvanometer and cell are interchanged at the balance point of the bridge ? Would the galvaometer show any current?
