Answers Latest () (Verified
Answers) Updated And A+ Graded
What does quiescent mean? - Correct Answer -Inactive; at rest, but ready to
operate.
Power supplies does what? - Correct Answer -Converts AC power to DC power.
A power supply contains five sections. What are they? - Correct Answer -Input,
rectifier, filter, regulator and protection.
Power supply input - Correct Answer -Applies AC signal.
Power supply rectifier - Correct Answer -Converts AC to pulsating DC.
Power supply filter - Correct Answer -Changes pulsating DC to smooth DC.
,Power supply regulator - Correct Answer -Maintains output voltage.
Power supply protection - Correct Answer -Prevents damage to power supply if
load shorts.
Which two parts of a power supply are optional? - Correct Answer -Regulator and
protection.
There are three types of rectifiers. What are they? - Correct Answer -Half wave,
full wave, bridge.
Describe a half wave rectifier. - Correct Answer -1 diode. Looks like a filter.
What is the output frequency of a half wave rectifier? - Correct Answer -Same as
input.
How many diodes does a full wave rectifier have? - Correct Answer -Two.
, Why is full wave more efficient than half wave? - Correct Answer -It uses the
entire input.
What is the output frequency of both a full wave and bridge rectifier? - Correct
Answer -Twice the input frequency (180° out of phase).
How many diodes does a bridge rectifier have? - Correct Answer -Four.
Which internal IC can produce signals that show three different volt levels? -
Correct Answer -Short between pins other than VCC and ground
TS relays and switches, sealed component and 2 types - Correct Answer -just
replace entire component, faulted mag coils and contacts
relays and swithces contacts TS, NO NC - Correct Answer -coned or cratered
(burned and pitted) burnishing tool, prevents out when E and prevents out when
de E.
Electrical TS common faults - Correct Answer -open or short, LED will not
illuminate if open or shorted
