Electrical Symbols — Power Sources

The vector stencils library "Power sources" contains 9 element symbols of power sources and batteries for drawing the electrical schematics and electronic circuit diagrams.
"A power supply is a device that supplies electric power to an electrical load. The term is most commonly applied to electric power converters that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (mechanical, chemical, solar) to electrical energy. A regulated power supply is one that controls the output voltage or current to a specific value; the controlled value is held nearly constant despite variations in either load current or the voltage supplied by the power supply's energy source.
Every power supply must obtain the energy it supplies to its load, as well as any energy it consumes while performing that task, from an energy source. Depending on its design, a power supply may obtain energy from:
(1) Electrical energy transmission systems. Common examples of this include power supplies that convert AC line voltage to DC voltage.
(2) Energy storage devices such as batteries and fuel cells.
(3) Electromechanical systems such as generators and alternators.
(4) Solar power." [Power supply. Wikipedia]

The vector stencils library "Computer peripheral devices" contains 18 clipart images of computer peripheral devices and equipment for drawing network diagrams.
"A peripheral is a device that is connected to a host computer, but not an integral part of it. It expands the host's capabilities but does not form part of the core computer architecture. It is often, but not always, partially or completely dependent on the host.
There are three different types of peripherals:
(1) Input, used to interact with, or send data to the computer (mouse, keyboards, etc.).
(2) Output, which provides output to the user from the computer (monitors, printers, etc.).
(3) Storage, which stores data processed by the computer (hard drives, flash drives, etc.)" [Peripheral. Wikipedia]
