Physics for IGCSE & O level - Magnets And Currents (Section 10 - No. 47)
What is the main difference between an A.C. and a D.C. generator?
A.C. generator uses a coil, D.C. does not.
A.C. generator uses slip rings, D.C. uses a commutator.
A.C. generators use a magnet, D.C. does not.
A.C. generators produce a stronger current.
설명
The main difference is the use of slip rings (A.C.) or a commutator (D.C.) to take out the current.
