It is called the loopdie loop circut.
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.
A complete loop for electrical flow is called a "circuit." In a circuit, electric current travels through conductive pathways, typically including components such as resistors, capacitors, and power sources. If the circuit is broken or incomplete, the flow of electricity will stop. Circuits can be classified as series or parallel based on how the components are arranged.
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 Series circuit
A simple circuit that has only one loop of wire is a series circuit. In a series circuit, the components are connected in a single path, forming a closed loop for the current to flow through. If one component fails, the entire circuit will be broken.
series circuit
That is described as a circuit in series, as opposed to a circuit in parallel, in which there is more than one loop.
A series circuit only has one loop
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.
an open 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.
In a simple circuit, there is typically one loop. This loop consists of a power source, such as a battery, connected to a load, like a resistor or light bulb, forming a closed pathway for current to flow. If there are additional components or branches, the circuit may have multiple loops, but a basic simple circuit is defined by a single loop.
A circuit in which all parts are connected in a single loop
I guess Electric Circuit....
