Electrical Engineering Flashcards
1
Q
capacitors
draw it
A
- stores electrical charge
- releases its stored charge
- stabilizes an unsteady power supply
2
Q
diodes
draw it
A
- allows current to flow only one way
- rectification ( A.C to D.C)
- emits light
- blocks current from traveling in opposite direction (PROTECTS battery)
ex. when u put batteries in backwards it wont workk
3
Q
transistors
draw it
A
- blocks or amplifies electric current
- C : current flows to E, through B like a door
- B : can stop or allow current to flow
ex. binary code
4
Q
relays
draw it
A
- controls high voltage circuit from a distance with low- volatge circuit
