What is an electric circuit and what are the different types?
WHAT IS AN ELECTRIC CIRCUIT AND WHAT ARE THE DIFFERENT TYPES
An electric circuit is an electric current that flows continuously. It is formed with the components consisting of conductors, such as wires, load element(s), such as a light bulb or a fan, and a power source, such as a battery. In order for an electric circuit to function properly, an electric circuit needs a source of power, conductors, load elements, conductors, and insulators. There are three different types of electric circuits. There is the series circuit, connecting load together is a series circuit, in the series circuit the electric current of each load in the circuit will be the same, but it will not be as powerful. There is also a parallel circuit. A parallel circuit is when the load elements are connected in just the right way so that the voltage in each is the same. Another type of circuit is a combination of the series and parallel circuits. A combination of both series and parallel circuits is a circuit with the laws of both parallel and series circuits. This circuit both lowers the voltage, and evenly distributes the electricity. Below is a picture of a power source giving off power to many load elements.

Insulators protect us from the harmful electric current flowing through a wire. Insulators are usually rubber, and rubber does not conduct electricity, which is why it is not a conductor, and because rubber insulates a conductor, it is an insulator. Insulators keep the electricity in the conductor, where it

A battery is a source of power. A battery is a marvelous tool to use in an electric circuit. The battery contains electrons, which, through conductors, gets passed on to the load elements in a circuit, and then the electric current flows back to the battery, where it originally came from, and then the battery keeps giving off power to the devices.
