11. Larger buildings may be supplied with a medium voltage electricity supply, and will required a substation or mini-sub. What is the main item of equipment contained in these?
Explanation : The transformer is used to transform a medium voltage supply to a low voltage supply, e.g. from 11 000 V to 400 V. A transformer is rated in kVA, kilo-Volt-Amps, which is a measurement of electrical power. Let us discuss.
12. Which is a type of Electrically-Erasable Programmable Read-Only Memory?
(a) Flash (b) Flange (c) Fury (d) FRAM
Answer
Answer : (a)
Explanation
Explanation : It’s commonly used for MP3 players, computer BIOS code and “thumb” drives. Originally developed in Japan by Toshiba, it has become quite popular for products requiring non-volatile erasable memory. Flash devices have a limited number of erase cycles (typically 10,000 to 1,000,000 cycles) so they’re not as good a choice for applications in which the data changes constantly. However, since it has no moving parts (unlike a hard disk) it is an excellent choice for storing the operating code for small personal electronics like PDAs, cell phones, digital cameras, and the data in items like MP3 players. Let us discuss.
