Trade Terms
An electrical current that changes direction 60/second or Hz
Alternating current
Pressure and flow of electric charge.
Electricity
A circuit that current can only flow one way.
Series circuit
Voltage X Amps =
Watts
A electrical device that produces voltage in a second circuit through electromagnetic induction.
Transformer
A material that conducts electricity.
Conductors
Power is measured in?
Watts

Series circuit
Amps X Resistance(ohms) =
Voltage
Electrically operated switches that open and close circuits by receiving signals from outside sources.
Relays
A continuous current path.
Continuity
The pressure that is put on free electrons that causes them to flow (EMF).
Voltage
The potential difference across each branch is the same ,but current flow may vary
Parallel
Volts/ Amps =
Resistance
A device for making and breaking an electric circuit
Contactor
The rate at which electrons flow in a circuit.
Current
Current flow is measured in.
Amps
The total resistance in this circuit will always be less then the value of the lowest resistance
Parallel circuit
Watts / Volts
Amps
A device in an electric circuit that stores electrical energy for later use.
Capacitor
A control device consisting of a coil and and set of contacts used as switching device in high voltage circuit.
Contactor
A force that counteracts the flow of current.
Resistance
Branches so that current divides and and part of it flows through any branch.
Parallel circuit
Amps x Resistance =
Voltage Drop
Microfarads
The rating of a capacitor
