does an ac generator need a slip ring. i did a past paper question and it said how did u create ac current at school. i talked about everything except commutators cause my school dosent have slip rings. is it correct if i dont talk about slip rings and is there such thing as an ac emf????

Big question sounds about right now.

Re: AC generators and AC voltage.

AC generator's need slip rings. A commutator wouldn't work at all for AC because of the direction required for the current.

Yes there is AC Voltage. This is called continuous/analog voltage and has many applications.

AC Voltage can be expressed as a curved graph of v (y-axis) vs t (x-axis). Any sinusoidal type graph or continuous graph of v vs t is showing AC voltage. So in fact the AC generator's output voltage is AC Voltage.

DC voltage is just a constant voltage which does not vary with time. It is a straight horizontal line on the graph v vs t.

Re: biggest question of 21st century

i was wondering why a thread with this title was in the physics forum

your username is appropriate lol

Re: AC generators and AC voltage.

Is this really a valid proof if you've only been doing it for 2 weeks? :L
(not hating, just found it funny)
Whole point of it was to be funny as if a first two weeks EE student can answer the biggest question of the 21st century. :haha:

So yeah I changed the name of the replying bit of the thread.

Its not proof for the generators bit (that's where B6 source comes into play).

Though we did the fundamental definitions and laws of electrics and electronics these two weeks, which covers the whole ac voltage thing I said.
