These are the basics and may even seem obvious or intuitive to you, such as the wires and if they are connected. Whenever you determine your specific field of electrical engineering, you may see more complex diagrams and symbols. You’ll learn also that different countries use different symbols. For example, of the two symbols for resistors above, the first one is used in the U.S., while the second is used in Europe. You will also learn about the various symbols used for switches, other power supplies, inductors, meters, lamps, LEDs, transistors, antennas, and much more.

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 Jessica Mireille. Diagram. Published at Monday, November 20th 2017, 03:57:49 AM. When working with circuits, you will often find something called a schematic diagram. These diagrams use symbols to illustrate what electronic components are used and where they’re placed in the circuit. These symbols are graphic representations of the actual electronic components.
By Charlotte Myriam. Diagram. Published at Monday, November 20th 2017, 03:19:30 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 Bertille Solange. Amplifier. Published at Monday, November 20th 2017, 03:11:46 AM. Unlike the Class A amplifier mode of operation above that uses a single transistor for its output power stage, the Class B Amplifier uses two complimentary transistors (either an NPN and a PNP or a NMOS and a PMOS) for each half of the output waveform. One transistor conducts for one-half of the signal waveform while the other conducts for the other or opposite half of the signal waveform. This means that each transistor spends half of its time in the active region and half its time in the cut-off region thereby amplifying only 50% of the input signal.
By Charlotte Myriam. Diagram. Published at Monday, November 20th 2017, 02:05:43 AM. Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.
