Question

null point is observed at 40cm from A. If a 2ohm resistor is added in parallel to S. The null point shifts to 25cm. Find R and S​

Answer 1

Answer:

a meter bridge, the null point is found at a distance of 40cm from A. If a resistance of 12Ω is connected in parallel with S, the null point occurs at 50.0cm from A. Determine the values of R and S. cbse class-12 Share It OnRead more on Sarthaks.com - https://www.sarthaks.com/55878/in-a-meter-bridge-the-null-point-is-found-at-a-distance-of-40cm-from-a
