Both of these examples illustrate the two common types of connections created in electric circuits. When two or more resistors exist in a circuit, then they can be linked in series or in parallel. The remainder of 4 will be dedicated to a study of both of these types of connections and the effect they have upon electric quantities like current, resistance and electrical potential. The next part of Lesson 4 can present the distinction between parallel and series connections.

Description with expressions: 3 D-cells are placed in a battery pack to power a circuit containing three bulbs. Employing the verbal description, an individual may obtain a mental picture of the circuit being described. But this time, the relations of light bulbs is achieved in a way such that there is a point on the circuit where the wires branch off from each other. The branching place is referred to as a node. Every light bulb is put in its own separate branch. These branch wires finally connect to each other to make another node. A single cable is used to link this second node into the negative terminal of the battery.

An electrical circuit is commonly described with mere words. On a lot of occasions in Courses 1 words have been used to spell out circuits. But another way of describing that the circuit is to simply draw it. Such drawings offer a faster mental snapshot of the true circuit. Circuit drawings such as the one below have been used several times in Lessons 1 through 3.

Description with expressions: Three D-cells are placed in a battery pack to power a circuit containing three bulbs. Employing the verbal outline, one can acquire a psychological picture of this circuit being clarified. This informative article can then be represented by means of a drawing of 3 cells along with three light bulbs attached by wires. Lastly, the circuit symbols introduced previously could be used to symbolize exactly the circuit. Note that three sets of long and short parallel lines are utilized to symbolize the battery pack with its own three D-cells. And note that every light bulb is symbolized with its own personal resistor symbol. Straight lines have been utilized to connect both terminals of the battery to some resistors and the resistors to one another.

The above mentioned circuits presumed that the three light bulbs were attached in this way in which the cost flowing through the circuit would pass through each one of the three light bulbs in sequential manner. The path of a positive test rate leaving the positive terminal of the battery along with also traversing the external circuit would involve a passage through every of the 3 joined light bulbs before returning to the side of the battery. However, is this the only method that the three light bulbs can be linked? Do they must be connected in consecutive fashion as shown previously? Surely not! In actuality, instance 2 below contains the exact same verbal description with the drawing along with the schematic diagrams being drawn differently.

A final way of describing an electrical circuit is by use of conventional circuit logos to offer a schematic structure of the circuit and its parts.

Just one cell or other energy source is represented by a long and a short parallel line. A collection of cells or battery will be represented by an assortment of short and long parallel lines. In both instances, the long point is representative of the positive terminal of this energy source and the short line signifies the negative terminal. A direct line is utilized to represent a linking cable between any two components of the circuit. An electric device that provides resistance to this flow of control is generically referred to as a resistor and can be represented by a zigzag line. An open button is usually represented by providing a break in a direct line by lifting some of the line upward at a diagonal. These circuit symbols will be frequently used throughout the remainder of 4 as electrical circuits are represented by schematic diagrams. It will be important to either memorize those symbols or to refer to this brief listing regularly till you are accustomed to their own usage.

So far, this unit of The Physics Classroom tutorial includes focused on the essential elements of an electric circuit and upon the notions of electric potential difference, resistance and current. Conceptual meaning of terms are introduced and applied to simple circuits. Mathematical connections between electrical quantities have been discussed and their use in solving problems has been modeled. Lesson 4 will concentrate on the means in which two or more electrical devices can be joined to form an electric circuit. Our discussion will advance from simple circuits into mildly complex circuits. Former fundamentals of electrical potential difference, current and resistance is going to be applied to those complex circuits and the same mathematical formulas will be employed to examine them.
