energy transfer
when energy moves from one place to another
pathway
ex; conducting wires that connect the two terminals of the battery
open and closed circuits
an open circuit is a circuit in which the path is incomplete which means there is no flow of current a closed circuit is a circuit in which the path is complete and there is a flow of circuit in the entire path
switch
a switch is an electrical component that is used to turn on and turn on and turn off any equipment like a television washing machine lights fans etc
electric current
electric current is a flow of electric charge from one place to another in circuit
electric circuit moodel
an electric circuit has to have a power source wires for the
insulators

conductors
substances that an electric charge can pass through without difficulty ex power lines fences for livestock battery jumper cables powering electrionic devices also copper aluminum iron steel gold and silver
source
such a a battery
user
such as a light bulb other device that uses energy
