When a conducting wire is connected in the right gap and known resistance in the left gap, the balacing length is 60 cm. the balacing length becomes 42.4 cm when the wire is stretched so that its length increases by

When a conducting wire is connected in the right gap and known resistance in the left gap, the balancing length is 60 cm. the balancing length becomes 42.4 cm when the wire is stretched so that its length increases by

When a conductor is connected in the left gap and known resistance in the right gap the balancing length is 50 cm. if the wire is stretched so that its length increased by 20% new balancing length is

When a wire is stretched to double its length, then

When a wire is stretched to double its length, then

When a conducting wire is connected in the left gap and known resistance in the right gap, the balance length is 75cm. If the wire is cut into 3 equal parts and one part isconnected in the left gap, the balance length
