End Of Course Test Questions

[Max Hudson]

Some State End Of Course questions for Electrical Technology that are questionable?
A current transformer should never be operated when:
1-The primary is disconnected
2-The secondary is disconnected
3-the primary is connected
4-The secondary is connected
When power is lost, high-intensity discharge lighting goes through a period before coming back on. This period is called:
1-Pre-heat period
2-Heating period
3-Cooling period
4-Standby period
A transformer is to be removed. Once the transformer has been isolated from all power sources, you should:
1-Disconnect the primaru first
2-Disconnect the secondary first
3-Ground out the primary and secondary
4-Loosen the taps
A typical use for a potential type relay in a control circuit would be to:
1-Aid the starting of a 3 phase motor
2-Aid the starting of a dc motor
3-Aid the starting of a synchronous motor
4-Aid the starting of a capacitor-start motor
An ac generator has a separate dc generator connected to the same shaft as the rotating field. This dc generator is called:
1-A shunt dc generator
2-An excitoe
3-A twin generator
4-A rectifyer
Please let me know which, if any response is correct for each question.

He is charged by the keystroke.

Maybe he is concerned that we members are charged for 'whitespace'.
