Learning objectives
(a) describe a simple form of a.c. generator (rotating coil or rotating magnet) and the use of slip rings (where needed)
(b) sketch a graph of voltage output against time for a simple a.c. generator
(c) appreciate similarities and differences between D.C generator and A.C. generator
(d) describe the structure and principle of operation of a basic iron-cored transformer as used for voltage transformations
(e) recall and apply the equation (Vs/Vp ) = (Ns/Np ) and Vs Is = Vp Ip (for ideal transformer) to new situations or to solve related problems
