Question 2 [Organization] The basic function of the system clock is to: synchronize external events All of these options are correct synchronize CPU and bus operations allow instructions for deferred completion O synchronize read and write accesses for identical delays 2.5 pts QUESTION 6 Parallel operation of two or more alternators on a common busbars is achieved among alternators first through synchronization and then load-sharing. a) (i) Why are alternators put in parallel anyway? (ii) What are the essential conditions for synchronizing two alternators? (iii) Draw a properly labelled diagram showing the synchronizing instruments employed with the synchronization (iv) Why must the synchroscope be switched off shortly after effecting synchronization? [4, 3, 10, and 2 marks] b) Two alternators are connected together on the main switchboard. Describe how one of them could be off- loaded and stopped for maintenance. [6 marks]
