When connected to an electronic circuit, an ideal voltage source maintains a given voltage between its two terminals by providing any amount of current necessary to do so. Similarly, an ideal current source maintains a given current to a circuit by providing any amount of voltage across its terminals necessary to do so.

Voltage nodes are single-terminal schematic components, which we can connect component terminals to in order to assign them to a specific voltage level. These are a special application of net names, meaning all terminals connected to a like-named voltage node are connected together.

Since single-layer/single-sided PCBs only have their various circuits and electrical components soldered onto one side, they are easy to design and manufacture. This popularity means that they can be purchased at a low-cost, especially for high-volume orders. The low-cost, high volume model means they are commonly used for a variety of applications, including calculators, cameras, radio and stereo equipment, solid state drives, printers and power supplies.

Examples of electronic output devices include computer monitors, LCD alphanumeric panels (as on a calculator), small lamps or light-emitting diodes (LED), etc. Digilent boards include different output devices, but all of them include some number of individual LED, and seven-segment LED displays that can display the digits 0-9 in each digit position (each segment in the seven-segment display contains a single LED). LED are two-terminal semiconductor devices that conduct current in only one direction (from the anode to the cathode). The small LED chips are secured inside a plastic housing, and they emit light at a givenfrequency (RED, YELLOW, etc.) when a small electric current (typically 10mA to 25mA) flows through them.

They consume electric power when energized, and they can function properly and do some meaningful work, or they can malfunction and create serious hazards to health and property. Even small circuits that are quickly and easily constructed still take time and money to build, and they can take a very long time to perfect.

You can think of a capacitor as a reservoir of charge that takes time to fill or empty. The voltage across a capacitor is proportional to the amount of charge it is storing – the more charge added to a capacitor of a given size, the larger the voltage across the capacitor. It is not possible to instantaneously move charge to or from a capacitor, so it is not possible to instantaneously change the voltage across a capacitor. It is this property that makes capacitors useful on Digilent boards and in many other applications.

Most of the electrical symbols can be changed in their appearance, styles and colors according to users requirements. Electrical symbols are used to represent various electrical and electronic devices in a schematic diagram of an electrical or electronic circuit.
