current
rate at which charges pass a given point
potential
energy per unit charge
the law of electric charges states:
like charges repel and opposite charges attract

consists of several cells
circuit
a complete, closed path through which electric charges flow
resistance
the opposition to the flow of electric charge
switch
used to open and close a circuit
cell
a device that produces an electric current by converting chemical energy into electrical energy
discharge
the loss of static electricity as charges move off an object
photocell
part of a solar panel that absorbs light and converts it into electrical energy
conduction
the transfer of electrons from one object to another
induction
rearrangement of electrons on an uncharged object without direct contact with a charged object
