A. thermal energy
B. magnetic energy
C. potential energy
D. mechanical energy

Answer 1

B. magnetic energy

Answer 2

Thanks! (:
Oh and nice, Johnny Bravo? HAHA

Answer 3

lol.

Answer 4

Which of the following can provide the energy source for a generator?

A. moving wind
B. moving water
C. steam
D. all of the above

Answer 5

This one? (:

Answer 6

Obv

D. all of the above

Answer 7

I didnt even read the lesson over >.<
OR the question LOL
Sorry.
I sm so stressed its not even funny

Answer 8

Two more?
According to Faraday's law, voltage can be changed by moving magnets away from the coil of wire.
True
False


When a generator rotates a coil of wire in a magnetic field, which of the following is produced?

A. magnetic domain
B. magnetic pole
C. electric field
D. electric current

Answer 9

both, pass/

Answer 10

>.<

Answer 11

lol

Answer 12

Nobody wanna give me the answers!!!
LOL
I don't blame them.
They prolly think I just don't wanna do the work,

Answer 13

I am concerned about the first one. I don't believe the answer furnished is correct.

Answer 14

There is normally motion relative to a coil and the magnetic field to create electrical energy. You will notice that electrical generators are powered either by gas engines, diesel engines, steam turbines, hydro etc. All of these provide rotation, and the rotation is mechanical. My choice would be mechanical for the first one.

Answer 15

the second one looks good.Third one, voltage will be induced when magnets are moved into or away from a coil of wire (relative motion) True.

Answer 16

The second one is current... changing magnetic field induces an emf (voltage) which in turn causes a current to flow

Answer 17

Voltage is induced in a coil by any changing magnetic field (change if the magnetic flux through it)

Answer 18

Last one I think is D. It is worded kind of funny. Would of made more sense if it was worded like this. When a coil of wire is rotated in the magnetic field of a generator which of the following is produced."

A generator gets it rotation from an external energy source. It more or less converts one kind of energy to electrical energy.
