By Madeleine Catherine. Diagram. Publised at Wednesday, July 05th 2017, 04:09:04 AM. A schematic shows connections in a circuit in a way that is clear and standardized. It is a way of communicating to other engineers exactly what components are involved in a circuit as well as how they are connected. A good schematic will show component names and values, and provide labels for sections or components to help communicate the intended purpose. Note how connections on wires (or "nets") are shown using dots and non-connections are shown without a dot.

When multiple components are connected in parallel, the total current is the sum of the currents flowing through each individual component. These statements are generalized as Kirchoff’s Current Law (KCL), which states that the sum of currents entering and exiting a node must be zero.

The most common form of capacitors is made of two parallel plates separated by a dielectric material. Charges of opposite polarity can be deposited on the plates, resulting in a voltage V across the capacitor plates. Capacitance is a measure of the amount of electrical charge required to build up one unit of voltage across the plates.

By Madeleine Catherine. Circuit. Published at Sunday, December 17th 2017, 00:43:41 AM. Resistors, capacitors, and inductors are the fundamental components of electronic circuits. In fact, all electronic circuits can be equivalently represented by circuits of these three components together with voltage and current sources.
By Valentine Sybille. Diagram. Published at Sunday, December 17th 2017, 00:08:54 AM. Circuits often require inputs that come directly from users (as opposed to inputs that come from other devices). User-input devices can take many forms, among them keyboards (as on a PC), buttons (as on a calculator or telephone), rotary dials, switches and levers, etc. Digilent boards include several input devices, typically including push buttons and slide-switches. Since digital circuits operate with two voltage levels (LHV or Vdd, and LLV or GND), input devices like buttons and switches should be able to produce both of these voltages based on some user action.
By Bertille Solange. Diagram. Published at Sunday, December 17th 2017, 00:06:10 AM. A digital circuit requires a power supply to provide a constant and stable source of electric power to all devices. As discussed above, electric power is derived from the basic electrical forces that charged particles (e.g., protons and electrons) exert on one another – namely, electrons are repelled by other electrons, and attracted to more electrically positive areas where there are relatively fewer electrons. The vast majority of charged particles are found in ordinary matter bound in electrically neutral atomic structures (that is, most particles are found in structures that have an equal number of positive and negative particles). Some electrically neutral conducting materials (like metals) contain electrons that are not so tightly bound to their host atoms. If a voltage source is applied to these materials, the lightly bound electrons will move away from the concentrated source of electrons on the negative side of the supply towards the electrically positive side of the supply. A “power supply” in a digital circuit provides a local, contained imbalance of electrons that provides a voltage source that can do useful work, such as transmitting information through a conductor from one device to another. A digital circuit allows a controlled flow of electrons from of the negative to positive side of the power supply, but only via the paths designed into the circuit. As electrons flow to and from the devices in a given circuit, they can change device properties in useful ways.
By Sasha Sara. Circuit. Published at Saturday, December 16th 2017, 23:35:56 PM. Voltage is measured in units of Joules per Coulomb, known as a Volt (V). It is important to remember that voltage is not an absolute quantity, rather, it is always considered as a relative value between two points. In an electronic circuit, the electromagnetic problem of voltages at arbitrary points in space is typically simplified to voltages between nodes of circuit components such as resistors, capacitors, and transistors
