Electricity the flow of electrons in a conductor
Autotransformer 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.
Current The flow of electrons through a circuit.
Direct Current (DC) Electricity flows in one direction
Battery Common source of DC current
Conventional theory of current flow The power supply creates flow from highest potential (positive terminal) to the
lowest potential (negative terminal).
United States power mains frequency? 60 Hz
Alternating Current (AC) Electricity flows alternately in one direction then in the other (cycles).

Circuit Tester Used to determine if electricity is present in a circuit.
4 basic components of an electrical circuit are: Power Supply, Input Device, Output Device, and Conductor
Regulation One feature power supplies are ussually designed to provide is a constant current
or constant voltage output.
Constant Current Power Supply Provides the same current level regardless of the demand placed on it by the
load.
Example of a constant voltage DC power supply Battery
Constant Voltage Power Supply Maintain a constant voltage output regardless of the load.
Electrical Diagrams Representation that shows how the components in a circuit are connected so that
we can understand what the circuit does and how it works.
Closed Circuit A complete path for current to flow from the positive terminal to the negative
terminal.
Open Circuit The path for the current is broken in some way.

Components of a switch Operater and Contacts
Switch a device that opens or closes a circuit
Normally open These contacts are open until acted upon by the operator.
Normally Closed These contacts are closed until acted upon by the operator.
Difference between N.O and N.C. contacts. Normally open switches break a current path until activated. Normally closed
switches complete a current path until activated.
Types of Operators Manually Operated and Automatically Operated
