There are none. Electrons must flow from the source, through the circuit, and back to the source or they don't move.
There are conductors other than wire, however. Best example is a car. You supply power to all the equipment in a car through wires and return the current through the car's frame.
The word 'circuit' means circle and is used with electricity for this very reason.

What is a circuit that only has one loop of wire?
series
What happens when the length of the wire in the series circuit is increased?
The current at every point in the series circuit becomes slightly less, because the increased length of wire adds slightly more resistance to the loop.
A magnet inside a wire loop can produce a current?
Only while the magnet is entering or leaving the loop. If you hold it still, no current is generated. The same goes for a longer magnet where the loop is being moved, but the magnet always remains inside the loop; no current.
How does a loop antenna work?
There are two types of loop antenna used in radio, small and large. It is a loop of wire usually circular or square with the circuit (transmitter or receiver) connected at the two adjacent open ends. A large loop is one wavelength in circumference and radiates a wave along the axis of the loop. It can also be thought of as a folded half-wave dipole. A small loop also known as a magnetic loop is one tenth of a wavelength or less in circumference and radiates in the plane of the loop. Used as a receiver, a small loop gives an output signal voltage proportional to the magnetic component of the arriving radio wave. Small loops for receiving can be made from a coil of wire on a ferrite rod, and this type of loop is also called a loopstick antenna. Intermediate-sized loops have a rather unpredictable pattern so tend not be used.
What is it called when a circuit that has only one path?
Electricity flows where there is a potential difference and some means of discharging that difference. A circuit is the loop of the thing causing the potential difference and the components that allow it to discharge. What seems to be confusing you is that the power source isn't always included in a circuit diagram. If you think in terms of a lighting circuit, the light comes on when the switch is closed. The part of the circuit inside your house only has the mains supply, some power switchgear, the light switch and the light. However, the circuit continues back through the supply cables to the generating station. Break the circuit at any point, in your house, under the street or a wire in the generator, and out goes the light.

When the electric current runs through the wire loop of a motor it makes a?
Circuit
Why are the live wire and neutral wire never joined together?
An electrical circuit forms a loop. The "live" or hot wire supplies the voltage, which is returned on the neutral. If the hot wire and neutral wire were connected together without a load between them, the circuit would be short out and trip the circuit's protection device.
Another name for a platinum wire loop?
oese
How can one close an open circuit?
One can close an open circuit by adding a complete loop of wire. This will allow the electricity to flow through the circuit, while electricity will not flow in an open circuit.
What happens when the length of the wire in the series circuit is increased?
The current at every point in the series circuit becomes slightly less, because the increased length of wire adds slightly more resistance to the loop.
What happens to the compass needle when you place it in the wire loop when the circuit was turn on?
it point same way as magnetic field
What happens to the compass needle when you place it in the wire loop when the circuit was turned on?

What is a branching circuit?
Each of the circuit breakers in the service panel controls electricity on a branch circuit. A branch circuit is typically a loop of wire that runs from the service panel, out to receptacles, light fixtures, appliances, etc. and back again.
What is the name of a machine that produces electricity by turning a loop of wire in a magnetic field?
A generator.
What number wire do you use to wire a washing machine outlet?
A 2C #14 will be suffice but it should be the only device on the circuit. This is known as a dedicated circuit.
Why doesn't the bulb light when one wire was loosen?
B/c electricity relies on there being a complete circuit for things to work. Break the circuit/loop, and the flow of electricity stops, and the light goes out.
