If the load current increases to the limiting value, the current limiting circuitry will take control and force the load current to the set limiting value (overriding the voltage error amplifier). The voltage error amplifier can resume control only if the load current is reduced sufficiently to cause the current limiting circuits to release control. This is covered in detail in the "Current Limiting" section.

You can think of a capacitor as a reservoir of charge that takes time to fill or empty. The voltage across a capacitor is proportional to the amount of charge it is storing – the more charge added to a capacitor of a given size, the larger the voltage across the capacitor. It is not possible to instantaneously move charge to or from a capacitor, so it is not possible to instantaneously change the voltage across a capacitor. It is this property that makes capacitors useful on Digilent boards and in many other applications.

By Cyrielle Marjolaine. Diagram. Published at Tuesday, November 14th 2017, 23:06:49 PM. An electronic circuit is a circular path of conductors by which electric current can flow. A closed circuit is like a circle because it starts and ends at the same point forming a complete loop. Furthermore, a closed circuit allows electricity to flow from the (+) power to the (-) ground uninterrupted.

Current is measured in the unit of Coulombs per second, which is known as an ampere (A). In an electronic circuit, the electromagnetic problem of currents is typically simplified as a current flowing through particular circuit components.

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.

Most of the electrical symbols can be changed in their appearance, styles and colors according to users requirements. Electrical symbols are used to represent various electrical and electronic devices in a schematic diagram of an electrical or electronic circuit.
