The figure shows 2 terminals M and N of a potential divider connected to a 6V battery. The circuit is connected to a Cathode-ray Oscillator.
(a) Describe in details what happens as the terminal is moved at a uniform speed from N to M.
(b) Draw the final reading of the final trace that is shown the CRO as N is moving towards M.
2. Relevant equations
3. The attempt at a solution
(a) As terminal N is moving towards M, there will be an increased in e.m.f, the results in a higher reading on the tracd
This is my attempt.
Please correct me if I make any mistakes. Thank you!
