how many main sources of energy are there
6
200
What can a Magnetic field be used for?
It produces an electric current
200
what does AC stand for?
Alternating Current
200
What does a step up transformer do?
it increases voltage and decreases current
200
name 2 of the electrical energy sources
any two will work
300
what is faraday's law?
electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force AKA electromagnetic induction
300
What does DC stand for?
Direct Current
300
What do step-down transformers do?
They decrease voltage and increases currents
300
What was the second fun fact question?(does not have to be word for word)
The largest generator(single) in the world is located in a power plant in china which can produce an outstanding 1750 megawatts of electricity, which is equal to 1,750,000,000 watts

Define Electromagnetic inductiuon
the process of generating a current by moving an electrical conductor relative to a magnetic field.
400
What is an Ac Current?
it is an electric current which periodically reverses direction
400
What is a transformer?
a device that changes voltage and current by inducing a changing magnetic field in one coil. This then induceses an alternating current in a nearby coil with a different number of turns.

when did Micheal Faraday discover electromagnetic induction
1831
500
What is a DC current?
it is the unidirectional flow of electric charge
500
how can power lose be reduced?
by using lower current transmitted at a higher voltage
500
Which type of generator is mostly used in the U.S. power plants?
AC Generators
500
what can a turbine be pushed by?
Air, water, or steam
