An electrical circuit can be defined as something which helps electrons to flow in a continuous uniform direction through wires. This flow of electrons occurs in a never ending loop without any source or destination. This cannot happen in a broken circuit. This loop should be made up of some conductive material.
FIVE THINGS
Ampere is the unit of measuring electric current.
Electric circuits are used to power bulbs or other electric components.
A battery is the major components of an electric circuit which acts as a power source. It provides energy which helps electrons to flow.
A battery consists of one or more section or cells. In every section, two electrodes are separated by a liquid or paste which is called electrolyte. Number of cells depends on the size of battery.
The amount of flowing electric charge in one second is called current.
In a circuit, electrons flow from negative to positive.
All the required components for formation of a circuit are: – battery, wires, bulbs, switches and motors.
A switch is used to control the flow of electricity. If a switch is open, it will create a gap in the circuit and current will not flow. When it is closed, circuit will be completed and flow of current will be continued.

Answer:
The cell is the small portion of living matter that constitutes the structural and functional unit of all living beings, formed by genetic material and cytoplasm and delimited by the plasma membrane that enables interaction with the environment.
Explanation:
All living beings are made up of basic units called cells; for this reason it is said that the cell is the structural unit of living beings. In the cell, all the functions and chemical reactions necessary for life are carried out; in addition, it participates in the reproduction processes. Different parts of the cell are distinguished, from the outside to its center. The fundamentals are: cell membrane (delimits and regulates), cytoplasm (organelles) and nucleus (DNA). The cell originates from a single cell, the egg or zygote, which occurs after the union of the gametes (ovum and sperm). Although many species of living beings are capable of reproducing without the participation of gametes, all in some generation do so through this mechanism. The cell is the simplest living being and, therefore, performs its three vital functions: nutrition (the function of uptake of matter and energy), relationship (the capture of stimuli and the emission of adequate responses) and reproduction. Cells have the ability to renew themselves either by growth or by reproduction, cell growth is limited to the manufacture of cellular materials, while reproduction allows the generation of new cells from existing ones. In unicellular organisms, new individuals originate; in multicellular cells, the number of cells increases, making possible the growth of the individual or the renewal of what had been damaged.
