For electricity to do useful work, it has to flow from a positive pole to a negative pole. (conventional current flow).
There has to be an electrical path between these two poles, provided by conducting wires and electrical components.
So the current flows from a source of electricity (say a battery), through the wires and components, then back to the same power sources other pole, in a circular fashion, completing the circle. Hence Circuit.
If a set of wires and components (say a lamp) completes this circle, such that when power is applied to the terminals, it works; then that set of wires and components is called a circuit.
If a stray wire connects straight across the power supply terminals, the power will take the least line of resistance and flow that way, instead of through the desired circuit.
This is then known as a short circuit. It takes the short path and does nothing useful, it takes as much current as possible, which ususally results in the wires overheating and catching fire.

What best describes continuity in a circuit?
Continuity in a circuit refers to the unbroken path for the flow of electric current. It ensures that there are no breaks or open circuits that could interrupt the flow of electricity. By testing for continuity, you can verify that all the components in the circuit are properly connected.
Closed path where electric current can flow is called a?
I guess Electric Circuit....
Compare magnetic circuit and electric corcuit?
A magnetic circuit describes the flow of magnetic flux through a material, typically consisting of a magnetic core and windings. An electric circuit, on the other hand, describes the flow of electric current through a path that includes components like resistors, capacitors, and inductors. Both circuits involve the transfer of energy, but magnetic circuits focus on the flow of magnetic fields, while electric circuits focus on the flow of electric charge.
What is the best definition of voltage?
Voltage is the difference in electric potential between two points in an electric circuit, representing the amount of potential energy available to move electric charge. It is measured in volts and determines the force or pressure that drives electric current through a circuit.
How can you start and stop electric circuit?
You can start an electric circuit by closing the circuit, typically by turning a switch on. You can stop an electric circuit by opening the circuit, usually by turning a switch off or disconnecting a wire.

What best describes electric currents?
The flow of electrons
What definition best describes myoelectric?
The term for electric properties of muscles.
What symbol would best represent an electric fan in an electric circuit?
An electric fan in an electric circuit is best represented by a simple symbol depicting a circle with blades inside, often resembling a propeller. This symbol indicates the fan's rotating mechanism while also showing its connection to the electrical circuit. Additionally, it may be accompanied by lines that represent the power supply connections.
Closed path where electric current can flow is called a?

The pathway taken by an electric current is a?
The term is "circuit" (from the same root as circle) An electric circuit must be uninterrupted for the current to flow. (This is why circuit-breakers are also called circuit-interruptors.)

What causes a electric current in a electric circuit?
Voltage causes current to flow in an electric circuit.
What is the history of the electric circuit?
the history of the electric circuit is that the person who made it his name is jack kilby but the history is that the electric circuit was one of the easiest way was to make the electric circuit when the electricity went out. THE END
