Independent sources are usually shown as a circle while dependent sources are usually shown as a diamond-shape. Independent sources can have a DC output or a functional output; some examples are a sine wave, square wave, impulse, and linear ramp. Dependent sources can be used to implement a voltage or current which is a function of some other voltage or current in the circuit. Dependent sources are often used to model active circuits that are used for signal amplification.

An electric current is defined as free flow of electrons and the motivating force behind that free flow of electrons is called Voltage. Voltage is the measurement of potential energy that would move the electrons between two points. Voltage is the push that the electrons require to move within a circuit. Voltage is measured by Volt and Current is measured by Ampere.

In some circuits, there are virtual grounds, which are nodes at the same voltage as ground, but are not connected to a power supply. When current flows into the virtual ground, the voltage at the virtual ground may change relative to the real ground, and the consequences of this situation must be analyzed carefully.

In addition, there needs to be a conductive path that provides a route for the electricity to flow. Finally, a proper circuit needs a load that consumes the power.
By Madeleine Catherine. Power. Published at Monday, December 18th 2017, 05:46:00 AM. Every electronic circuit is designed to operate off of some supply voltage, which is usually assumed to be constant. A voltage regulator provides this constant DC output voltage and contains circuitry that continuously holds the output voltage at the design value regardless of changes in load current or input voltage (this assumes that the load current and input voltage are within the specified operating range for the part).
By Jessica Mireille. Circuit. Published at Monday, December 18th 2017, 05:40:39 AM. Most electronic circuits can be represented as a system with an input and an output. The input signal is typically a voltage that is generated by a sensor or by another circuit. The output signal is also

By Madeleine Catherine. Diagram. Published at Monday, December 18th 2017, 04:49:04 AM. A digital circuit is constructed of a power supply, devices, and conduction nets. Some nets provide circuit inputs from the “outside world”; in a schematic, these input nets are generally shown entering the left side of component and/or the overall circuit. Other nets present circuit outputs to the outside world; these nets are generally shown exiting the schematic on the right. In the sample schematic below, circuit components are shown as arbitrary shapes, nets are shown as lines, and inputs and outputs are denoted by connector symbols.

As fluid flows through a pipe, frictional drag forces at the walls dissipate energy from the flow and thus reducing the pressure, or equivalently, the potential energy of the fluid in the pipe. A small resistor is equivalent to a large diameter pipe that will allow for a high flow rate, whereas a large resistor is equivalent to a small diameter pipe that greatly constricts the flow rate.
By Cyrielle Marjolaine. Circuit. Published at Sunday, December 17th 2017, 15:08:00 PM. Surface mount PCBs do not utilize wires as connectors. Instead, many small leads are soldered directly to the board, meaning that the board itself is used as a wiring surface for the different components. This allows circuits to be completed using less space, freeing up space to allow the board to complete more functions, usually at higher speeds and a lighter weight than a through-hole board would allow.
