Electrical Engineering
electrical components correct answersused to control flow of electricity to produce desired
outcome
What is an Electrical Engineer? correct answers- One who designs, develops & maintains
electrical control systems/components
What do Electrical Engineers focus on? What are their priorities? correct answerseconomy
safety
reliability
quality
sustainability
How do electrical engineers communicate designs? correct answersElectrical Diagrams:
- Pictorial Diagram
- Wiring Diagram
- Schematic Diagram
What are Printed Circuit Boards? correct answersused to mechanically support & electrically
connect electronic components using conductive pathaways
wire correct answersconductor of electrical current
toggle switch correct answerswhen "open" - disrupts flow of current
pushbutton switch correct answerswhen pushed, circuit is completed, current can flow
Relay correct answersuses voltage to control another voltage
transistor correct answerssemiconductor used to amplify/switch electronic signals & electrical
power
Resistor correct answersreduces flow of current
variable resistor correct answersa controllable resistor, usually with 2 terminals
photo cell correct answersconverts light energy into electricity
diode correct answersallows current flow in 1 direction
capacitor correct answersused to store electrical charge
inductor correct answerscoil that generates magnetic field
battery correct answerssource of power/voltage
voltmeter correct answersmeasures voltage, has high resistance, connected in parallel
lamp/light bulb correct answersemits light when current flows through
Light Emitting Diode "LED" correct answersemits light when current flows through
electrical motor correct answerselectrical machine that converts electrical energy into mechanical
energy
fuse correct answersprotects circuits from high current, breaks/disconnects when high current
flows
buzzer correct answersproduces buzzing sound (audio signal device)
"Source"
"Path"
"Load" correct answersSource = Battery
Path = Wire
Load = Lightbulb
Ohm's Law correct answersshows relationship between ohms (Resistor, "R"), watts (Power, "P"),
volts (Voltage, "E") & amperes/amps (Current, "I")
I = E/R
