CBSE Class 12-science Answered
In case of motional EMF induced in a loop due to the sliding of a rod over a U shaped conducting wire, we consider the case where the velocity of the rod is constant. Why do we not consider a case where velocity is changing w.r.t time i.e., where an acceleration comes into play? Also, in the methods of inducing emf, why don't we consider a change in velocity of the coil (linear in case of a rod sliding over U shaped wire and angular in case of the rod rotating)?

Expert Answer
We can definitely consider the scenario wherein the velocity is changing.
However, the emf induced on the loop will not remains constant and will constantly change.
This will make the measurement of emf very difficult.
