1. Electricity - Correct Answer: the flow of electrons in a conductor
2. Autotransformer - Correct Answer: Uses only one coil for the primary
and secondary. It uses special connections on the coil called taps to produce
the different ratios and voltages.
3. Current - Correct Answer: The flow of electrons through a circuit.
4. Direct Current (DC) - Correct Answer: Electricity flows in one direction
5. Battery - Correct Answer: Common source of DC current
6. Conventional theory of current flow - Correct Answer: The power supply
creates flow from highest potential (positive terminal) to the lowest
potential (negative terminal).
,7. United States power mains frequency? - Correct Answer: 60 Hz
8. Alternating Current (AC) - Correct Answer: Electricity flows alternately in
one direction then in the other (cycles).
9. Circuit Tester - Correct Answer: Used to determine if electricity is
present in a circuit.
10.4 basic components of an electrical circuit are: - Correct Answer: Power
Supply, Input Device, Output Device, and Conductor
11.Regulation - Correct Answer: One feature power supplies are ussually
designed to provide is a constant current or constant voltage output.
12.Constant Current Power Supply - Correct Answer: Provides the same
current level regardless of the demand placed on it by the load.
13.Example of a constant voltage DC power supply - Correct Answer:
Battery
14.Constant Voltage Power Supply - Correct Answer: Maintain a constant
voltage output regardless of the load.
,15.Electrical Diagrams - Correct Answer: Representation that shows how
the components in a circuit are connected so that we can understand what
the circuit does and how it works.
16.Closed Circuit - Correct Answer: A complete path for current to flow
from the positive terminal to the negative terminal.
17.Open Circuit - Correct Answer: The path for the current is broken in
some way.
18.Components of a switch - Correct Answer: Operater and Contacts
19.Switch - Correct Answer: a device that opens or closes a circuit
20.Normally open - Correct Answer: These contacts are open until acted
upon by the operator.
21.Normally Closed - Correct Answer: These contacts are closed until acted
upon by the operator.
22.Difference between N.O and N.C. contacts. - Correct Answer: Normally
open switches break a current path until activated. Normally closed
switches complete a current path until activated.
, 23.Types of Operators - Correct Answer: Manually Operated and
Automatically Operated
24.Function of the operator on a manual switch? - Correct Answer: Allows
you to change the states of the contacts of the switch.
25.Common application of a knife switch? - Correct Answer: Main
disconnect switch for incoming power to a large machine.
26.A knife switch consists of? - Correct Answer: Lever (operator) that
conducts the current and one or more sets of contacts.
27.A Pushbutton switch consists of: - Correct Answer: Pushbutton-type
operator and one or more sets of contacts.
28.Momentary Switches - Correct Answer: Switches with a spring return.
29.Selector Switch - Correct Answer: A switch with an operator that is
rotated to activate the electrical contacts.
30.5 electrical output devices: - Correct Answer: Lamp, Resistor, Buzzer,
Solenoids, and Motors
31.Lamp - Correct Answer: A lamp or indicator light gives off light when
electrical current flows through its resistive (usually wire) element.
