A collection of electronic components that have been assembled and interconnected to perform a given function is commonly referred to as a circuit. The word circuit derives from the fact that electric power must flow from the positive terminal of a power source through one or more electronic devices and back to the negative terminal of a power source, thereby forming a circuit. If the connections between an electronic device and either the positive or negative terminals of a power supply are interrupted, the circuit will be broken and the device will not function.

Notice that a parallel-connected motor delivers performance identical to a series-connected motor running at twice the power supply voltage.

Completing an electrical engineering degree and then getting a job in the field means you will see a lot a lot a lot of these schematics. It’s important to understand exactly what is going on with these. While they can (and will) get very complex, these are just a few of the common graphics to get your footing on.

The concept of complex impedance introduces a unified representation for resistors, capacitors, and inductors, whereby a circuit’s frequency response from input to output can be determined using KVL and KCL, where each element is assigned the appropriate impedance. The key assumption to this point is that the input to the circuit must consist solely of DC and/or sinusoidal signals. Now, this analysis is be extended to include arbitrary input signals by using the mathematical techniques of Laplace transforms.

As discussed earlier, a digital circuit represents and manipulates information encoded as electric signals that can assume one of two voltages – logic-high voltage (or Vdd) and logic-low voltage (or GND). A digital circuit requires a power supply that can produce these two voltages, and these same supply voltages are also used to encode information in the form of two-state, or binary signals. Thus,if a given circuit node is at Vdd, then that signal is said to carry a logic ‘1’; if the node is at GND, then the node carries a logic ‘0’. The components in digital circuits are simple on/off switches that can pass logic ‘1’ and logic ‘0’ signals from one circuit node to another. Most typically, these switches are arranged to combine input signals to produce an output signal according to basic logic relationships. For example, one well-known logic circuit is an AND gate that combines two input signals to produce an output that is the logic AND of the inputs (i.e., if both input1 and input2 are a ‘1’, then the output is a ‘1’).

By Lydie Honorine. Circuit. Published at Thursday, November 02nd 2017, 19:35:35 PM. Electronic signals are represented either by voltage or current. The timedependent characteristics of voltage or current signals can take a number of forms including DC, sinusoidal (also known as AC), square wave, linear ramps, and pulsewidth modulated signals. Sinusoidal signals are perhaps the most important signal forms since once the circuit response to sinusoidal signals are known, the result can be generalized to predict how the circuit will respond to a much greater variety of signals using the mathematical tools of Fourier and Laplace transforms.

Semiconductor diodes can be designed to produce direct current (DC) when visible light, infrared transmission (IR), or ultraviolet (UV) energy strikes them. These diodes are known as photovoltaic cells and are the basis for solar electric energy systems and photosensors. Yet another form of diode, commonly used in electronic and computer equipment, emits visible light or IR energy when current passes through it. Such a device is the familiar light-emitting diode (LED).
By Bertille Solange. Diode. Published at Saturday, October 28th 2017, 18:33:02 PM. When an analog signal passes through a diode operating at or near its forward breakover point, the signal waveform is distorted. This nonlinearity allows for modulation, demodulation, and signal mixing. In addition, signals are generated at harmonics, or integral multiples of the input frequency. Some diodes also have a characteristic that is imprecisely termed negative resistance. Diodes of this type, with the application of a voltage at the correct level and the polarity, generate analog signals at microwave radio frequencies.
