The essential difference between an AC generator and a DC generator is that a. AC generator has an electromagnet while
a DC generator has a permanent magnet.
b. DC generator will generate a higher voltage.
c. AC generator will generate a higher voltage.
d. AC generator has slip rings while the DC generator has a commutator.
d. The AC generator has slip rings, while the DC generator has a commutator.
AC generators have two rings known as the slip rings, while DC generators have two half rings known as the commutator. This is the main difference between AC generator and DC generator.

Explain the underlying principle and working of an electric generator by drawing a labeled diagram. What is the function of brushes?
State the rule to determine the direction of an
(i) magnetic field produced around a straight conductor carrying current,
(ii) force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it, and
(iii) current induced in a coil due to its rotation in a magnetic field.
Two circular coils A and B are placed closed to each other. If the current in coil A is changed, will some current be induced in the coil B? Give a reason
