In a parallel circuit, all devices receive the same:
Voltage
A device that increases or decreases voltage
Transformer
A material that limits the flow of charge particles.
Insulator
The flow of charged particles
Electric Current

Electric Circuit
Where does most of the electrical energy used in your home come from?
Power Plants
A closed circuit in which the current divides into two or more paths before recombining to complete the circuit.
Parallel Circuit
A measure of the energy for an amount of charge
Voltage
The cell in a batter that produces electricity.
Electrochemical Cell

Electric Force
What do the long straight lines represent on a circuit map?
A closed circuit in which the voltage is shared among the loads.
Series Circuit
Conductor
The greater the voltage of a battery, the (larger/smaller) the amount of energy a charge may acquire.
