Voltage
potential difference; the measure of PE per unit charge between 2 points in an electric field
Clouds are
made of water vapor (containing protons and electrons)
Electric Current
the build up of different charges
Polarization
the separation of protons and electrons (going to opposite sides)
The ground contains
a positive charge that allows it to attract negative charges from the atmosphere
Energy used for only positive charges
will not produce a current because there is no flow of charge
Work Energy Theorem
the work done equals the energy used
If energy used beecomes PE
it can be used to do work
Voltage must
exist for a current to flow
Current
the flow of negative charges towards positive charges
