Description with Words: 3 D-cells are set in a battery pack to power a circuit comprising three light bulbs. Utilizing the verbal description, one can obtain a mental image of the circuit being described. But this moment, the relations with light bulbs is achieved in a manner such that there is a point on the circuit in which the cables branch off from each other. The branching place is referred to as a node. Each light bulb is put in its own branch. These branch wires finally connect to each other to produce a second node. A single cable is used to connect this second node to the negative terminal of battery.

An electrical circuit is described with mere words. Saying something like"A light bulb is connected to a D-cell" is really a sufficient amount of words to spell out a very simple circuit. On many occasions in Lessons 1 through 3words are used to spell out circuits. But another means of describing that the circuit is to draw it. Such drawings provide a quicker mental picture of the actual circuit. Circuit drawings like the one below have been used several times in Courses 1 through 3.

Thus far, this unit of The Physics Classroom tutorial has concentrated on the crucial elements of an electric circuit and upon the notions 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 and their use in resolving issues has been modeled. Lesson 4 will concentrate on the way by which a couple of electric devices can be joined to form an electrical circuit. Our discussion will advance from simple circuits into somewhat complex circuits. Former principles of electrical potential difference, resistance and current is going to be applied to those intricate circuits and exactly the exact mathematical formulas are employed to analyze them.

Employing the verbal outline, an individual can get a mental picture of this circuit being clarified. This verbal description can then be represented by means of a drawing of 3 cells and three light bulbs attached by wires. The circuit logos might be utilized to represent the same circuit. Note that three sets of short and long parallel lines have been used to represent the battery package with its own three D-cells. And note that every light bulb is represented with its own individual resistor symbol. Straight lines have been used to connect the two terminals of the battery to some resistors and the resistors to each other.

These two examples illustrate the two common kinds of connections created in electric circuits. When two or more resistors are present in a circuit, then they may be connected in series or in parallel. The remainder of 4 will be dedicated to a report on these two different types of connections and also the impact that they have upon electric quantities like current, resistance and electric potential. The next portion of Lesson 4 can introduce the distinction between parallel and series connections.

A final means of describing an electrical circuit is by usage of traditional circuit symbols to supply a schematic structure of this circuit and its elements.

Just one cell or other energy source is represented with a very long and a short parallel line. An assortment of cells battery is represented by a collection of long and short parallel lines. In both instances, the extended 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 linking cable between any two elements of this circuit. An electrical device that provides resistance to the flow of control is generically referred to as a resistor and is represented by a zigzag line. An open switch is generally represented by providing a rest in a straight line by lifting a portion of the line upward in a diagonal. These circuit logos will be frequently used throughout the remainder of Lesson 4 as electrical circuits have been represented by assessing diagrams. It will be very important to either memorize these symbols to consult with this brief listing frequently till you are accustomed to their use.

The above mentioned circuits presumed that the three light bulbs were attached in such a way in which the cost flowing through the circuit could pass through every one of the 3 light bulbs in sequential manner. The course of a positive test rate leaving the positive terminal of the battery along with traversing the external circuit would demand a passing through each one of the three connected lighting bulbs prior to returning into the negative terminal of the battery. But is this the only solution that the three light bulbs can be joined? Do they have to be connected in consecutive fashion as shown previously? Absolutely not! In reality, instance 2 below includes the identical verbal description with the drawing and the schematic diagrams being drawn otherwise.
