Resistor

Resist the flow of current
Change voltage in a circuit

1

Transistor

Acts as a switch
Selectively blocks/passes current; control a secondary current

2

Capacitor

Store charge
Pulse of current or timing

3

Diode is also known as...

LED

4

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)

5

Ohms law

Involves current, voltage, and resistance

6

How to find resistance?

Voltage over current
