Current Electricity
Sources of energy
Voltaic (or galvanic) cell
Converts chemical energy to electric energy
A battery is multiple galvanic cells connected
Photovoltaic cell
Changed light energy to electric energy
Conservation of charge
Charge cannot be created or destroyed but it can be separated
total amount of charge in a circuit does not change
Paths
Series
One circuit path
Parallel
Multiple circuit paths
Electric Current
Flow of charged particles
Electric Circuit
Any closed loop or conduction path allowing charge to flow
Power
Rate at which energy is transferred
Conventional current
Flow of positive charge
Charges flow from high to low potential and stop once potential difference reaches zero
