Electrical Action Fuzes Flashcards
What are transistors?
Electronic switches and the base leg turns on
What is a Silicon Controlled Rectifier (SCR)?
A Latching Electronic Switch
How does a R/C circuit work?
Timed resistor / Capacitor
What can a photo cell detect?
Light in various spectrums
What function does the base leg of a transistor do?
It is the trigger / switch
What does a 555 circuit look like?
Spider or Japanese battle flag
What does IC stand for?
Integrated Circuit
What does a resistor and capacitor pair together have in common with a 555 chip?
They are timers
Name a few products that you can find a IC chip in?
- Amplifiers - Timers - Oscillators - Voltage Regulators
- Microprocessors - Memories - Microcomputers
What are some ID features of a remote control?
Multiple batteries, receiver, braided wire, servos, micro switch, antenna “may or may not be present”
What do resistor / capacitors and 555 timers have in common?
They are all timing devices
What are the indicators of a remote controlled device?
Antennas, servos and battery packs, braided wires
What function does the base leg of a transistor do?
Turns the transistor on allowing current to flow
What causes a collapsing circuit to function?
Battery decay, cutting the wrong wire, or anti-disturbance
What causes movement of the contacts in a relay?
The energizing/de-energizing of the coil
