How do you charge an object?  PHET Simulations Demo
https://phet.colorado.edu/sims/html/balloons-and-static-electricity/latest/balloons-and-static-electricity_en.html
CHARGING BY CONDUCTION (direct contact)
1) Rubbing materials together TRANSFERS ELECTRONS
from the atoms of one object to the other object
 Example: the balloon acquires electron from the sweater
when rubbed and becomes negatively charged
2) Touching a charged object to a neutral object
makes them share charges equally
 Example: Touching negatively charged rod to
neural metal sphere transfers half the extra
electrons to the sphere

How do you charge an object?
3) CHARGING BY POLARIZATION (no contact!)
Bringing a charged object close to a neutral object
REDISTRIBUTES the ELECTRONS inside the neutral
object.
The neutral object is still electrically neutral.
 Example: charge a balloon by rubbing it on your hair
and see how it sticks to the wall  why?

LEDs are semiconductor light sources
What does that mean?!
Lets figure it out by recalling what we already know:
 What is a Conductor? (Hint: Why dont we make wires from

 What is a Superconductor? (A lot of hype about them! Why?)
 What is a Semiconductor? (Put it all together)
LED = Light Emitting Diode

Conductor vs. Insulator
If all things are made of
atoms, why do some
materials conduct electricity
and others do not?
The electrons in the atoms of
insulators are not free to move!
Conductors have free (or
loosely-bound) electrons that can
move!
