Thought of the day_Oct26

Whether K is open or close the balance length will be the same. There is no current flowing through the standard cell at balance length . Hence whether K open or close has no effect on pd across R1.
If the balance length is 0.75L where L is the length of AB. What is the pd across the wire AB with a standard cell of 1.0 V?
