STATIC DISCHARGE

STATIC DISCHARGE

Static Discharge

• When there is a big difference between charges in
  two nearby objects, electrons will jump (static
  discharge) from the more negative object to the
  less negative object.

Why we feel shocks

• Water molecules in the air collide with you
  during the humid months and take away some of
  that electrical charge as they collide with us.
• Dry winter weather ? less water molecules in air

Safety
During storms, the water molecules in the clouds
become charged when they collide with each other
(friction). The negative charges (electrons)
move to the bottom of the cloud. The negative
charges in the cloud induce charge on the earth
by making the electrons in the ground (earth) go
further down. Positive molecules and atoms are
left at the surface of the earth. When there is
a big enough difference between the clouds
negative charges and the earths positive
charges, the electrons from the ground jump
(static discharge) from the cloud to the earth.
The light you see goes up from the earth to the
clouds on the same path.
