Electrical Fuzes Flashcards
What is the function of a diode?
Allow current to flow one-way.
What is a transistor?
An electronic switch.
A resistor and capacitor equals
A timer.
A 555 chip looks like
A spider or Japanese battle flag.
What can a photocell detect?
The presence or absence of light, including infrared.
What function does the base leg of a transistor do?
It turns on or triggers the switch.
What does IC stand for?
Integrated circuit.
What does a resistor and capacitor pair together have in common with a 555 chip?
They both control time.
What are the indicators of a remote controlled device?
Antennas, servos, and battery packs, braided wires.
What causes a collapsing circuit to function?
Battery decaying, cutting the wrong wire, or antidisturbance.
What does a PIR switch detect?
Temperature changes in detection zones and movement.
How are capacitors used?
As power sources or as timing devices.
How are active infrared devices activated?
By interrupting the infrared beam.
