Ionisation is the ability to remove electrons from atoms leaving a trail of positive ions.

DISCHARGING UNSAFE STATIC
Electrons are transferred fromthe pipe to the fuel by friction.
A high voltage could cause an explosion so:* Fuel tank is earthed with a copper conductor* fuel tank and plane are connected

HOW A PHOTOCOPIER WORKS
ORIGINAL Copying plate is charged
ORIGINAL isprojected onto copying plate
Light makescharge leakaway
Black powder attaches to remaining charges
Powder is transferred to copying paper

Light makescharge leakaway
Black powder attaches to remaining charges
Powder is transferred to copying paper
Paper is heated to ‘fix’ image
