Cards in this deck (36)
- 1is used to refer both to the study of electronics technology and to the equipment and devices that contain electronic componentselectronics
- 2electricity flows easily through itconductor
- 3very high resistance to the flow of electricityinsulators
- 4is a fundamental atomic particleelectron
- 5is the flow of electronsCurrent
- 6Current is measured in units calledamperes (abbreviated A)
- 7is the electrical pressure that forces electrons to flow through a mediumVoltage
- 8Voltage is measured in units calledVolts
- 9is the opposition to current flow presented by a mediumResistance
- 10Resistance is measured in units calledohms (Ω)
- 11are used by technicians as a form of “shorthand” to show how components are connected in circuitsschematic diagram
- 12The heating element in a toaster is made of a material callednichrome
- 13The heating element’s property of opposing electric current causes it to get very hot when current flows through itresistive element
- 14the schematic symbol that’s used to represent the heating element in the diagram is the symbol for aresistor.
- 15The resistive element in this type of resistor is carbon that’s mixed with some nonconducting substancecarbon resistor
- 16uses nichrome wire as the resistive elementwirewound resistor
- 17(AC)alternating current
- 18(DC)direct current
- 19reverses direction, repeatedly as it flows through the circuitalternates
- 20One complete reversal of the AC current flow is called acycle
- 21The rate at which the cycles occur is called thefrequency
- 22Frequency is measured in units calledhertz(Hz)
- 23The process of rectification is accomplished in many electronic circuits by a component calleddiode
- 24The action of converting AC current to DC current is calledrectification
- 25diodes are often calledrectifiers
- 26The two ends of a diode are calledthe anode and the cathode
- 27are a broad group of components that are used to convert some kind of environmental event into electrical signalsSensors
- 28The sensor component that’s used in this type of application is calledthermistor
- 29is an electronic component that’s used in many devices todaytransistor
- 30several different types of transistorsthe base, the emitter, and the collector
- 31The most basic operation of the transistoramplification
- 32the circuit components are connected to circuit paths etched on the circuit boardprinted circuit board
- 33a printed circuit board consists of a thin sheet of copper that’s laminatedinsulating board or substrate
- 34The components will be mounted from the substrate side of the boardcomponent side
- 35The other side of the board that contains the conducting paths is calledfoil side
- 36these same photographic techniques were greatly refined and applied to the field of electronics to produceintegrated circuit
