## What is a series circuit?

Thus far, this unit of The Physics Classroom tutorial has focused on the critical components of an electric circuit and upon the concepts of electric potential difference, current and resistance. Conceptual meaning of terms are introduced and implemented to simple circuits. Mathematical relationships between electrical quantities are discussed along with their use in resolving problems has been modeled. Lesson 4 will concentrate on the means in which a couple of electrical devices can be connected to form an electric circuit. Our conversation will advance from simple circuits to somewhat complex circuits. Former fundamentals of electric potential difference, resistance and current is going to be applied to these complex circuits and exactly the identical mathematical formulas are used to examine them.

Electric circuits, whether simple or complex, can be explained in a variety of ways. An electrical circuit is described with mere words. On several occasions in Courses 1 words are used to spell out simple circuits. But another means of describing a circuit is to simply draw on it. Such drawings offer a faster mental snapshot of the true circuit. Circuit drawings like the one below are used several times in Class 1 through 3.

Utilizing the verbal outline, an individual could acquire a mental picture of the circuit being described. However, this moment, the relations of light bulbs is achieved in a way such that there's a stage on the circuit in which the wires branch away from every other. The branching location is known as a node. Each bulb is set in its own independent branch. A single wire is used to connect this second node to the negative terminal of battery.

The aforementioned circuits presumed that the three light bulbs were connected in such a manner that the charge moves through the circuit would pass through each of the 3 light bulbs in sequential manner. The path of a positive test rate departing the positive terminal of the battery along with traversing the circuit would involve a passage through each one of the three connected light bulbs before returning into the negative terminal of the battery. However, is this the only method that three light bulbs can be connected? Do they must get connected in consecutive fashion as shown previously? Surely not! In actuality, illustration 2 below includes the exact verbal description with the drawing along with the schematic diagrams being drawn differently.

Description with Words: Three D-cells are placed in a battery pack to power a circuit comprising three light bulbs. Utilizing the verbal description, one can acquire a psychological picture of the circuit being described. This informative article can then be represented by a drawing of 3 cells and three light bulbs connected by wires. Last, the circuit logos can be used to represent the circuit. Be aware three sets of long and short parallel lines are utilized to symbolize the battery pack with its three D-cells. And note that every light bulb is represented by its own personal resistor symbol. Straight lines have been utilized to link the two terminals of the battery into some resistors and the resistors to one another.

These two examples illustrate the two common types of connections created in electrical circuits. When a couple of resistors are present in a circuit, then they can be linked in series or in parallel. The rest of 4 will be dedicated to a study of these two kinds of connections and also the impact they have upon electric quantities such as current, resistance and electrical potential. The next portion of Lesson 4 will soon present the distinction between parallel and series connections.

Just one cell or other energy source is represented with a long and a short parallel line. An assortment of cells or battery is represented by a collection of long and short parallel lines. In both situations, the long line is representative of the positive terminal of the energy supply and the brief line signifies the negative terminal. A direct line is used to symbolize a connecting wire between any two components of the circuit. An electrical device that provides resistance to this flow of charge is generically referred to as a resistor and is represented by a zigzag line. An open button is usually represented by giving a rest in a direct line by lifting some of the line upward in a diagonal. These circuit symbols are frequently used throughout the remainder of 4 as electric circuits are represented by multiplying diagrams. It'll be significant to either memorize these symbols to refer to the short listing regularly till you become accustomed to their own use.

A final means of describing an electrical circuit is by use of traditional circuit symbols to provide a schematic structure of the circuit and its components.
