| An energy source | battery,power plant, thermocouple, photocell, generator |
| Wires | to conduct electrons and connect the different parts of circuit |
| A resistance | light bulb, appliance, machine, motor - converts current into heat, light or mechanical energy |
| A switch | opens and closes circuit allowing a path for electrons to flow |
| Series | -all the parts are connected one after another -only one path for electrons to flow -a break in any circuit will stop electron flow -ex. holiday tree lights |
| parallel | -different parts of the circuit are on separate branches -several paths for electrons to flow-if there is a break in one branch, electrons can still move through other branches |
| Electric Current | the flow of charged particles |
| Conductors | Allow electrons to flow easily through them |
| Voltage | the amount of energy required to move a charge between two points |
| Voltage | the amount of energy required to move a charge between two points |
