A drawing of an electrical or electronic circuit is also referred to as a circuit diagram, but can also be referred to as a schematic diagram, or simply schematic.

Circuit Symbols and Physical Components. Each digital or electric element is represented by a symbol as can be found in this very simple circuit structure. Lines used to connect the symbols represent conductors or cables. Each symbol represents a physiological element that may look as follows.

Listed below are general circuit design rules.

• Lines or pliers from circuit diagrams are often vertical or horizontal. In some cases a diagonal line could be used that is placed in 45 degrees.
• Component symbols at a circuit structure are often placed horizontally or vertically. On very rare occasions a part might be placed at 45 degrees, but just for a very good reason.
• Circuit diagrams have been drawn as simply and neatly as possible. This usually means that the physical implementation of the circuit might appear different to the circuit structure, but they are exactly the same.
• Lines linking parts can be thought of insulated wires in most instances, with just the ends of these cables being bare conductors for electrical connection.
• When lines cross each other in a circuit diagram, they can be thought of as two insulated wires crossing if there is no node in which the wires intersect or cross each other.
• Three lines intersecting at a point using a node in the junction means that the 3 wires are electrically connected. This connection could be considered as three insulated wires bared in the point of junction and glued together.
• Two cables that cross each other with a node at the junction of the crossing point means that the wires are connected.
• Circuit or schematic diagrams contain symbols representing bodily elements and lines representing cables or electric conductors. To be able to understand to read a circuit design, it is required to understand what the schematic symbol of a component appears like. It is also vital to understand how the parts are joined together in the circuit.

A component list can now refer by reference designator to these components. A node is simply a filled circle or dot. If three or more lines touch each other or mix each other plus a node is placed at the junction, this represents the lines or wires being electrically connected at that point.

Physical Circuit. The physical circuit to the above circuit diagram might look something similar to the image below, but a more practical physical circuit would have a light bulb holder and knobs that connect with the battery terminals. A light bulb holder would have screw terminals to connect the wires to, along with a socket to screw the light bulb into. Battery presses would enable the cables to easily be connected between the battery and light bulb holder.

Following a four part introduction, the very first tutorial from the electronics course shows the circuit diagram of a very simple LED and resistor circuit and the way to build it upon breadboard.

Component References. Components at a circuit must always have testimonials, also called reference designators, used to recognize the components in the circuit. This enables the components to readily be referenced in text or a component listing.

When starting to learn to read digital circuit diagrams, it is imperative to learn what the schematic symbol looks like to get many different electronic elements. Adhering to the course explains how to examine basic electronic circuit diagrams while constructing the circuits on electronic breadboard. The class contains a listing of basic electronic components using their schematic symbols in which beginners can learn exactly what the physical components and their symbols look like.

Fundamental components for this tutorial include a LED, resistor and battery life that can all be found from the newcomer's component reference.

The bottom terminals of these bulbs are connected to each other and to the negative terminal of the battery life, because the next node indicates that these connections.

If lines or wires cross each other and there's not any node, as shown in the base of the aforementioned picture, the cables aren't electrically connected. In this case the wires are crossing each other with no joining, like two insulated wires placed you on top of the other.

Series Circuit Example. No nodes are essential in this circuit to reveal the bulbs linking to each other and to the battery because single wires are connecting straight to one another. Nodes are just placed in case three or more wires are attached.

Specifying Components. Typically the true battery kind and bulb kind would be defined in a component list that communicates the circuit structure. More information about the battery and bulb sort might also be contained in the circuit as text. For example, the battery might be specified as a 12.8V 90Ah Lithium battery, plus even a 9V PM9 batterycharger. The light bulb might be specified as a 12V 5W incandescent bulb, or 9V 0.5W torch bulb.

Parallel Circuit Example It may be noted that the best terminals of both light bulbs are all connected together and into the positive terminal of the battery. We understand this because the three terminals or link points possess a node where they intersect.

Another light bulb at the circuit will then have the reference designator L2.

The ideal way for novices to continue learning how to read circuit diagrams would be to stick to the path and build the circuits from each tutorial.

Battery and Light Bulb Circuit. Probably the simplest circuit that may be drawn is one which you might have seen in a college science class: a battery attached to a light bulb as shown under.
