The output resistance (also known as source resistance) of a voltage regulator is a close cousin of its load regulation. Figure 1 illustrates how the output voltage of a regulator typically changes as a function of load current. Initially, the slope is quite linear but once the load current becomes higher than the design then the voltage will often drop rapidly with an increase in current. We measure the output resistance only on the linear portion of the plot in the normal operating region. It is meaningless to use a point in the overload area as that will result in an artificially high output resistance.

By Sasha Sara. Diagram. Published at Tuesday, July 25th 2017, 11:46:43 AM. 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.
By Cyrielle Marjolaine. Diode. Published at Saturday, July 22nd 2017, 10:45:28 AM. A diode is a specialized electronic component with two electrodes called the anode and the cathode. Most diodes are made with semiconductor materials such as silicon, germanium, or selenium. Some diodes are comprised of metal electrodes in a chamber evacuated or filled with a pure elemental gas at low pressure. Diodes can be used as rectifiers, signal limiters, voltage regulators, switches, signal modulators, signal mixers, signal demodulators, and oscillators.

The control circuitry must monitor (sense) the output voltage, and adjust the current source (as required by the load) to hold the output voltage at the desired value. The design limit of the current source defines the maximum load current the regulator can source and still maintain regulation.

The purpose is the same: getting from point A to point B. Literally, a circuit is the path that allows electricity to flow. If you know what to look for, it’ll become second nature. While at first you’ll just be reading them, eventually you will start creating your own. This guide will show you a few of the common symbols that you are sure to see in your future electrical engineering career.
By Valentine Sybille. Circuit. Published at Monday, July 10th 2017, 06:11:26 AM. If the components of the circuit are connected in one single path is it termed as series. The same current would flow through all the components while the voltage would differ from one component to another. For example you have lit three lamps in series to the same power source, the first one would receive more voltage than the last.
