Final Flashcards
(21 cards)
Transistor
Acts as a switch
Selectively blocks/passes current; control a secondary current
Resistor
Resist the flow of current
Change voltage in a circuit
Capacitor
Store charge
Pulse of current or timing
Diode is also known as…
LED
Diode
Semi conductor
Only allows current to flow in one direction
Used to regulate flow of electricity
Used to make power supplies (AC/DC convertor)
Ohms law
Involves current, voltage, and resistance
How to find resistance?
Voltage over current
How to find voltage?
Current times resistance
How to find current?
Voltage over resistance
AC power
Is an alternating current
Positive/negative switch
Wall circuits are examples
DC power
Flows in one direction
Batteries are examples
