DC Generator Fundamentals

Questions and Answers

What is the function of an electrical generator?

An electrical generator converts mechanical energy into electrical energy.

What is the basis of energy conversion in DC generators?

The energy conversion process in DC generators is based on the principle of production of dynamically induced emf.

Match the following terms related to DC generators with their definitions:

DC generator = A machine that converts mechanical energy into electrical energy Dynamically induced emf = An emf produced in a conductor when it cuts the magnetic field Fleming’s Right Hand Rule = A rule used to determine the direction of induced emf in a generator Magnetic field = One of the essential parts of an electrical generator Signup and view all the answers

Match the following parts of an electrical generator with their functions:

Magnetic field = Produces a field of force in which the conductor moves Conductor = Cuts the magnetic field and produces dynamically induced emf Fleming’s Right Hand Rule = Used to determine the direction of induced emf Dynamically induced emf = Causes a current to flow if the conductor circuit is closed Signup and view all the answers

Match the finger in Fleming’s Right Hand Rule with its corresponding action:

Thumb = Points in the direction of induced emf Forefinger = Points in the direction of the magnetic field Middle finger = Does not have a specific action in the rule None of the fingers = Does not exist in the rule Signup and view all the answers
