Engine 2014: Electricity

1. A produce the alternator field excitation current associated with no-load operation
2. B smooth out transient voltage spikes and dips associated with sudden load changes
3. C produce additional excitation current beyond the no-load current inversely proportional to the actual load current
4. D produce additional excitation current beyond the no-load current proportional to the actual load current
