By definition an electrical circuit is a route or path that starts and finishes at the same place. So there is no part of an electrical circuit that is not necessary, because if there were it would not be an electrical circuit.

An electrical circuit needs a power source. Conductors to transmit the voltage from the power source to the load. The final component of the electrical circuit is the load that you want to energize.


If you remove any of the components there will be an open circuit and the load will be impossible to operate.

What an incomplete circuit?

An incomplete circuit is an open circuit; i.e. some part of the circuit isn't connected to anything.Or think of it like this: A circuit is complete when there exists a complete (or closed loop) path for the electrons to flow through it. Also known as a closed circuit. If this is not the case, then it is an incomplete (or open) circuit.


What happens if one bulb in a series circuit burned out?

In a series circuit, all bulbs are necessary to complete the circuit. If one bulb goes out, the circuit is broken, so none of the bulbs would light up.


What best describes a necessary condition of a series circuit?

the complete and total absence of any point in the circuit where the current has any choice of which way to go ... no 'forks in the road'

Is a ground wire necessary for a complete circuit?

No, the ground wire is there for safety reasons and only carries current in fault conditions.


A complete electric circuit includes a voltage source current wires and something to ground the flow of current?

If you ground the flow of current like the last part of your question states you will not have a complete circuit as the circuit will open on a short circuit. To make a complete circuit operate you need a power source, an overload device to protect the conductors of the circuit, conductors to carry the current and a load across the power source which causes the current to flow in the circuit. Leave any one of these things out and you will not have a complete circuit.
