Hello World for a Circuit
Light and LED
Parts:
Battery
Resistor
LED
Why:
Power Source
An LED will light up when enough voltage is supplied but can also burn out if too much is allowed to pass through. The resistor will limit the voltage to prevent damage.

They each have a physical property that interacts with electricity. When put in combination various actions occur.
What are resistors?
Resistors provide a specific amount of resistance to a path in a circuit or wire. Ohm's law is used to calculate the properties related to resistance.
Ohm's Law: I = V/R
I = Current measured in Amps
V = Voltage measured in Volts
R = Resistance measured in Ohms
Resistors are color coded.
