What does an electric circuit mean?

Hint:This is a simple direct question. A simple definition of an electric circuit is a network consisting of a closed-loop that gives a return path to the current flowing. The current flowing should be able to go from one terminal of the power source to the other. The complete definition is in the step-by-step solution.

Complete answer:
An electrical circuit is a network consisting of a closed-loop that gives a return path to the current flowing. The current flowing should be able to go from one terminal of the power source to the other. An electric circuit consists of a power source and linear lumped elements. The power source is the cause for the current to flow; it can be a voltage source or a current source. A battery is a source of power. Linear lumped elements are resistors, capacitors, and inductors.

An electric circuit must have a power source and any number of different linear lumped elements. Linear lumped elements are used to vary the current or voltage flowing in the circuit based on the requirements. A resistor opposes the flow of current. Causing the current to decrease.

Capacitors store energy in the form of an electrostatic field between its plates. Inductors store energy in the form of magnetic energy. It is a conductor turned into a coil, this generates a magnetic field in a clockwise direction. Transformers work on the principles of an inductor, to transfer current without contact. An electric circuit requires a conductor through which the current can flow. Conductors are metals that have low electrical resistance.

Note: There are two different types of electrical circuits. They are parallel and series circuits. They are used based on their purpose. An electric device and an electric circuit are two different things. An electric device has a clot of electric circuits that form an electric device.
