NEET 2019 (Odisha)
Options:
Answer:
B
Solution:
The emf generated due to a rotating conductor in a generator is given by where, magnetic flux linked with conductor From the above equation we can conclude that the emf generated is a varying function of time with opposite polarity. So, all the graph are correct for the given variations.
