Q)
In a metre bridge , the balance point is found to be at $39.5\;cm$ from the end A, when the resistor Y is of $12.5 \;ohm$. Determine the resistance of x. Why are the connections between resistors in a metre bridge made of thick copper ships ? What happens if the galvanometer and cell are interchanged at the balanced point of the bridge ? would the galvanometer show any current?
