Unit 12 conduction in liquids and gases
What is the most important factor in the ionization of a gas?
Electron impact
Conduction in a Liquid depends on the movement of
Ions
What is a negative ion? Positive ion?
Negative ions are atoms that gained extra electrons. Positive ions are atoms that are electrons deficient
What is the negative/ positive terminal of a power source called?
