Chapter 1: Generate Electrical Energy

Flashcards covering generators, Faraday's contributions, and the principle of induction.

Generator

A device that uses mechanical energy to create electrical energy.

What are some sources of mechanical energy used to create electrical energy

Wind turbines, water turbines, gas turbines, internal combustion engines and even hand cranking are sources of mechanic energy used to create electrical energy

Michael Faraday

A scientist, physicist, and chemist who created the first electromagnetic generator in 1831.

What is the Faraday Disc is know for?

The Faraday Disc is considered the first electromagnetic generator.

How does the Faraday Disc generator work?

The Faraday Disc generator works by producing a small amount of direct current (DC) as the copper disc rotates between the poles of a magnet shaped like a horseshoe.

What is Faraday's Law of Electromagnetic Induction (EMI)

The fundamental principle behind the operation of any electrical generator.

Faraday’s Law of Electromagnetic Induction or simply Induction predicts what?

The interaction between a magnetic field and an electric circuit that produces an electromotive force (EMF). This is the definition of induction.

What is induction?

Induction is a process by which an electrical conductor becomes electrified when near a charged body. Induction is also a process by which an electromagnetic force (EMF) is produced in a circuit by varying the magnetic field linked with the circuit.

Electromotive Force (EMF)

A difference in potential that gives rise to an electric current.
