ATT Comp Test (FC) Exam With Detailed Questions and All Correct Answers
A _______ ________ fuse will typically blow in about one second, while a ________ ________ could
take 1-30 seconds. - Fast acting; slow blow
A complete short in the secondary transformer will ____________ secondary voltage. - eliminate
A partial short in the primary of the transformer will _____________ secondary voltage. - Increase
A power supply contains five sections. What are they? - Input, rectifier, filter, regulator and protection.
A step-down transformer _____________ output voltage in the secondary. - decreases
A step-up transformer ___________ output voltage in the secondary. - increases
A/an ___________ is a component that has the ability to concentrate a magnetic field. - inductor
An IC's internal malfunctions make its operation _______________. - unpredictable
An open in the primary of a transformer won't do what? - Produce current in the secondary.
An open in the secondary of a transformer prevents an output voltage in _____ _________
________________. - the open secondary
An open wire will measure ___________ resistance. - maximum
, Applied voltage - Sum of all voltage drops in the circuit.
Arc burns are what? - Electrical current flowing through tissue or bones
Are capacitors circuit protection devices? - No.
Base - Very thin and lightly doped, allows most current carriers to pass between emitter to collector.
Collector - Moderately doped, largest area, dissipates heat. Receives most current carriers.
Current flowing through a relays contacts in one direction can only cause what failure? - Coned and
cratered contacts.
Current is defined as __________________________. - a flow of electric charge
Current is measured in an open circuit when the leads are placed in what way? - Across the open.
Describe a half wave rectifier. - 1 diode. Looks like a filter.
Electrical burns are what? - Electrical current flowing through tissue or bones
Electrical TS common faults - open or short, LED will not illuminate if open or shorted
Emitter - Heavily doped so it emits larger # of current carriers inside semi conductive material.
Factors of electrical accidents - Unsafe equipment, unsafe environment, and unsafe work practices
