An electrical circuit is usually described with mere words. Saying something like"A light bulb is linked to some D-cell" is really a decent quantity of words to spell out a very simple circuit. On several occasions in Courses 1 through 3, words are used to describe circuits. Upon hearing (or reading) the phrases, a individual grows accustomed to quickly picturing the circuit within their mind. But another way of describing that the circuit is to draw it. Such drawings offer a quicker mental snapshot of the real circuit. Circuit drawings such as the one below have been used several times in Lessons 1 through 3.

Description with Words: 3 D-cells are placed in a battery pack to power a circuit containing three bulbs. Employing the verbal explanation, one may acquire a mental image of the circuit being clarified. But this moment, the relations with light bulbs is achieved in a fashion such that there is a stage on the circuit in which the wires branch away from each other. The branching location is known as a node. Each bulb is placed in its own independent division. A single wire is used to connect this second node to the negative terminal of the battery.

Both of these examples illustrate the two common types of connections made in electrical circuits. When two or more resistors exist in a circuit, they can be linked in series or in parallel. The remainder of 4 will be dedicated to a study of these two kinds of connections and the impact they have upon electrical quantities such as current, resistance and electric potential. The next part of Lesson 4 can soon introduce the distinction between series and parallel connections.

The above circuits assumed that the 3 light bulbs were attached in this manner in which the rate flowing through the circuit would pass through each of the 3 light bulbs in sequential mode. The path of a positive test charge leaving the positive terminal of the battery along with also hammering the circuit would involve a passage through every one of the 3 joined light bulbs prior to returning into the negative terminal of the battery. But is this the sole method that three light bulbs could be linked? Do they have to get connected in consecutive fashion as shown above? Absolutely not! In actuality, example 2 below comprises the identical verbal description together with the drawing along with the schematic diagrams being drawn differently.

Description with expressions: Three D-cells are placed in a battery pack to power a circuit containing three bulbs. Utilizing the verbal explanation, one can acquire a mental picture of the circuit being described. This informative article can then be represented by means of a drawing of 3 cells along with three light bulbs connected by cables. The circuit symbols introduced previously can be employed to symbolize the circuit. Be aware that three sets of long and short parallel lines are used to symbolize the battery package with its three D-cells. And note that every light bulb is symbolized by its own individual resistor emblem. Straight lines are used to connect the two terminals of the battery to some resistors and the resistors to one another.

A single cell or other power supply is represented by a long and a brief parallel line. A collection of cells battery can be represented by an assortment of long and short parallel lines. In both instances, the extended point is representative of the positive terminal of this energy source and the short line represents the terminal. A straight line is used to symbolize a linking cable between any two components of the circuit. An electric device that provides resistance to the flow of charge is generically referred to as a resistor and can be symbolized by a zigzag line. An open switch is usually represented by providing a break in a straight line by lifting a portion of the line upward in a diagonal. These circuit logos are frequently used throughout the remainder of Lesson 4 as electric circuits are represented by multiplying diagrams. It will be important to either memorize those symbols to consult with this short listing frequently till you are accustomed to their usage.

A final method of describing an electrical circuit is by usage of traditional circuit symbols to provide a schematic diagram of this circuit and its parts. A few circuit symbols used in schematic diagrams are shown below.

Thus far, this particular unit of The Physics Classroom tutorial includes concentrated on the critical 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 relationships between electrical quantities have been discussed along with their use in solving problems has been modeled. Lesson 4 will concentrate on the way in which two or more electric devices can be connected to form an electrical circuit. Our conversation will progress from simple circuits to somewhat complex circuits. Former fundamentals of electrical potential difference, current and resistance is going to be applied to these complex circuits and exactly the same mathematical formulas will be employed to examine them.
