Rate of flow of electrical charge is called current P2 4.2 Charge on the move Metals conduct electricity because they contain conduction or de-localised electrons To which terminal of a cell (battery) are the electrons attracted ?

Electrons in the metal object are repelled by the negatively charged rod Because ‘like charges repel”

Electrons in the metal object are repelled by the negatively charged rod Because ‘like charges repel” If the rod touches the conductor electrons flow off the rod and onto the conductor leaving both objects negatively charged

ELECTRICAL DISCHARGE A charged conductor can be discharged by connecting it to earth. + -

If the voltage is high enough the air molecules will ionise and a spark discharge occurs. - Ionisation is the ability to remove electrons from atoms leaving a trail of positive ions. Electrical potential energy or potential difference between the conductor and the ground
