energy 2 Flashcards
energy transfer
when energy moves one from a another
pathway
ex conducting wires that connect the two terminals of battery
open and closed circuits
open circuits an open circuit is a circuit in which the path is incomplete which means there is no flow of current closed circuit a closed circuit is a circuit in which the path is completeand there is a flow of current in the entire path
switch
a switch is an electrical component that in used to turn on and to turn off any equipment like a television washing machine and there is a flow of current in the entire path
electric current
