Draw a neat labeled diagram of a.c. generator. What is the magnitude of emf induced in the coil when its plane becomes parallel to the magnetic field?

A conducting loop is placed just straight in current carrying conductor. Find the direction of induced current, if any, when current in straight wire is (i) increasing (ii) decreasing (iii) steady?

Name the parts A, and B of the transformer shown in figure.

State whether this transformer is step-up or step-down?
