Releasing Electrical Charges

Releasing Electrical Charges



Electric
discharge is the
rapid transfer of
electrons from
one object to
another.

How many ways are there for a charged
object to become neutral again?

Releasing Electrical Charges
There are 2 main ways to discharge an object:

1) Contact/grounding
2) Sparking




                                                4

1) By contact/grounding

Discharging by contact means touching a charged
  object to an object with the opposite charge so
  they may neutralize each other.

Releasing Electrical Charges
1) By contact/grounding

Grounding a charged object will add or remove as
  many electrons as required to make it neutral.

2) Sparking.

A spark occurs when an object becomes so charged
  that it is able to move or pull electrons over a
  distance in order to become neutral.               7

2) Sparking

Lightning is a large-scale example of releasing an
   electrical charge via a spark.

2) Sparking

The bottoms of clouds become negatively charged
  during a storm. The ground then becomes positively
  charged by induced charge separation.

2) Sparking

Eventually electrons are forced down from the sky into
  the positively charged ground.
