Electrical Symbols — Power Sources
A voltage source(power sources) is a two terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply unlimited current. A voltage source is the dual of a current source. Real-world sources of electrical energy, such as batteries, generators, and power systems, can be modeled for analysis purposes as a combination of an ideal voltage source and additional combinations of impedance elements.

An electrical source is a device that is capable of converting non-electric energy to electric energy and vice versa. Electricity is most often generated at a power station by electromechanical generators, primarily driven by heat engines fueled by chemical combustion or nuclear fission but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power and electrochemical batteries.

It doesn’t matter what kind of business you have, a bar or a gym, there are common concepts for any of them. One of those concepts is accounting, and to facilitate the work with the figures, you can use accounting flowchart symbols and create a clear and representative scheme. You can create flowchart for auditing, tax accounting and even for planning your own budget.
A graphical tool for displaying successive processes is flowchart. This method is mostly suited to represent an accounting process. The sequence of steps in the accounting process usually consists of standard accounting procedures, that can be depicted by using a minimal number of symbols, applied for the basic flowcharting. The advanced opportunity to create professional Accounting Flow charts is provided by ConceptDraw Accounting Flowcharts solution. It includes contains a library of accounting flowchart symbols used when drawing the accounting process flow.

Cisco switches and hubs deliver the best performance, and often used as network solutions for small businesses, enterprises, data centers. Cisco switches are the core interconnect devices of each computer network. The numerous Cisco switches specifically designed for various applications. Network switches are separated for two types: fixed configuration and modular switches. The fixed configuration switches deprecate swapping or adding another module, and vice versa for modular switch.

In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance to the flow of current in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. Today, most diodes are made of silicon, but other semiconductors such as selenium or germanium are sometimes used.
