This is a picture of a power strip. A power strip is a nice way to think of a parallel circuit. A parallel circuit is a closed circuit in which the current divides into two or more paths before recombining to complete the circuit. Therefore if something is wired in a parallel circuit and i unplugged my computer charger, my fan, light, and other computer charger would remain on. The other type of circuit is a series circuit. A series circuit is an electric circuit connected so that the current passes through each circuit element in turn without branching. In other words if you unplugged one item they would all turn off.
