It is called the loopdie loop circut.
Series circuit
When the lamps are in a loop, one after the other: we call this a series circuit.
A closed circuit in which the current divides into two or more paths before recombining to complete the circuit.
It will oscillate if the loop gain exceeds 1 when the phase difference round the loop is 360 degrees. The frequency of oscillation is set by the loop phase being equal to 360 degrees.
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.
A simple circuit consists of a source of electro motive force ( EMF or voltage V ) This could be a battery,dynamo or solar cell. The circuit should do something, like light a lamp. For the lamp to glow there must be a flow of electrons called an electric current measure in Amperes (I). For the current to flow the circuit must form a closed loop, like a daisy chain. A switch is a device that breaks this loop and controls the state of the circuit. Closed circuit, switch closed, = lamp on Open circuit, switch not closed = lamp off
A Series circuit
series circuit
series
You probably mean, What is a circuit?It is something that goes in a loop like an electrical circuit, the electrons flow in a loop. A hydraulic circuit, the fluid flows in a circle from one point then back again.
I guess Electric Circuit....
When the lamps are in a loop, one after the other: we call this a series 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.
A circuit in which all parts are connected in a single loop
The simplest circuit is a single loop of components connected in series; that is, the components are connected head to tail, with the first and last components connected to close the loop and complete the circuit. See the nearby link for the most rudimentary series circuit imaginable.
In a single loop circuit (series circuit) this will be an open circuit. If there is a current loop of some type, there's a complete path already, and thus no classification such as open or short circuited. It simply an incomplete circuit.
A parallel circuit
It is a series circuit with all the components connected in series.
