What would you expect to happen if one electronics device stopped working in a series circuit?

If one electronic device goes out within a series circuit, then all the other electronic devices that are a part of that series circuit would also go out.


A series circuit is a closed circuit that allows for only one path through which a current can flow. An old fashioned string of Christmas lights is an excellent example of a series circuit. When one light goes out, the circuit is "opened" and the flow of electricity stops at the location of the burned-out light bulb. Another type of circuit is a parallel circuit.


Parallel circuits are closed circuits that have two or more paths through which a current can flow. If one item of the circuit goes out, then that part of the parallel circuit will no longer work. However, the current can still travel through the other paths of the parallel circuit. This allows other electronic devices to continue working even when one goes out. Therefore, most household wiring is composed of parallel circuits.
