How can we charge insulators?
TERM
Image
- By rubbing them together as long as they are
made from different materials. (friction)
- Rubbing objects together removes the
electromagnetic forces of attraction.
- electrons are transferred from one object to the
other
- One becomes positively charged and the other
negatively charged
- The object that gains / loses electrons depends on
the material
DEFINITION
Insulators
TERM
Image
Do not conduct electricity:
, - Electrons cannot flow throughout the material
- Fixed electrons
DEFINITION
Conductors
TERM
Image
Conduct electricity because their electrons
- Can FLOW
- Are DELOCALISED
i.e: Metals, graphite
DEFINITION
Practical: investigate how insulating materials can
be charged by friction
TERM
Image
Suspend one of the insulating materials using a
cradle and a length of string so that the material
can rotate freely.
Rub one end of the material using a cloth (in order
to give it a charge).
