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.

Sometimes, to make schematics more legible, we’ll give a net a name and label it, rather than routing a wire all over the schematic. Nets with the same name are assumed to be connected, even though there isn’t a visible wire connecting them. Names can either be written directly on top of the net, or they can be “tags”, hanging off the wire.

This is a set of multiple electronic circuits on a small semiconductor device (normally silicon). With the advancement of technology, these IC’s prove to be extremely beneficial. They are present in any electronic device you can name. From computers, mobiles to other digital appliances you have multiple IC’s present in them. Their main components are a combination of Diodes, transistors and microprocessors. The microprocessors provide memory to the device. With the help of the microprocessor the electronic devices can perform logical or protocol applications.

By Charlotte Myriam. Circuit. Published at Sunday, December 24th 2017, 12:55:04 PM. 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.
By Bertille Solange. Diagram. Published at Sunday, December 24th 2017, 12:18:52 PM. If there’s something on a schematic that just doesn’t make sense, try finding a datasheet for the most important component. Usually the component doing the most work on a circuit is an integrated circuit, like a microcontroller or sensor. These are usually the largest component, oft-located at the center of the schematic.
By Cyrielle Marjolaine. Circuit. Published at Sunday, December 24th 2017, 11:56:04 AM. When multiple components are connected in series, each component must carry the same current. When multiple components are connected in parallel, the total current is the sum of the currents flowing through each individual component. These statements are generalized as Kirchoff’s Current Law (KCL), which states that the sum of currents entering and exiting a node must be zero.
