Electricity and Magnetism
Success criteria
• I can identify sign and nature of charge
carriers and their drift speed in a metal.
• I can solve problems using the drift
speed equation
Usually, there are no carriers
Should occur ionization first,
then the current
There can be other ionizing
factors… e.g. radioactivity, heat…
