Electrical Engineering Quiz

Electrical Engineering Quiz electrical components - used to control flow of electricity to produce desired outcome What is an Electrical Engineer? - - One who designs, develops & maintains electrical control systems/components What do Electrical Engineers focus on? What are their priorities? - economy safety reliability quality sustainability How do electrical engineers communicate designs? - Electrical Diagrams: - Pictorial Diagram - Wiring Diagram - Schematic Diagram What are Printed Circuit Boards? - used to mechanically support & electrically connect electronic components using conductive pathaways wire - conductor of electrical current toggle switch - when "open" - disrupts flow of current pushbutton switch - when pushed, circuit is completed, current can flow Relay - uses voltage to control another voltage transistor - semiconductor used to amplify/switch electronic signals & electrical power Resistor - reduces flow of current variable resistor - a controllable resistor, usually with 2 terminals photo cell - converts light energy into electricity diode - allows current flow in 1 direction capacitor - used to store electrical charge inductor - coil that generates magnetic field battery - source of power/voltage voltmeter - measures voltage, has high resistance, connected in parallel lamp/light bulb - emits light when current flows through Light Emitting Diode "LED" - emits light when current flows through
