Many regulators (and most LDO regulators) specify only a single value of maximum current. This value is guaranteed for any input/output voltage within the maximum ratings for the part.

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.

It is important to remember that voltage is not an absolute quantity, rather, it is always considered as a relative value between two points. In an electronic circuit, the electromagnetic problem of voltages at arbitrary points in space is typically simplified to voltages between nodes of circuit components such as resistors, capacitors, and transistors
By Valentine Sybille. Circuit. Published at Saturday, December 23rd 2017, 04:05:50 AM. There are two kinds of energy sources in electronic circuits: voltage sources and current sources. 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.

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 Bertille Solange. Diagram. Published at Saturday, December 23rd 2017, 03:33:27 AM. An electronic circuit is a circular path of conductors by which electric current can flow. A closed circuit is like a circle because it starts and ends at the same point forming a complete loop. Furthermore, a closed circuit allows electricity to flow from the (+) power to the (-) ground uninterrupted.
By Bertille Solange. Diagram. Published at Saturday, December 23rd 2017, 03:21:07 AM. Variable resistors and potentiometers each augment the standard resistor symbol with an arrow. The variable resistor remains a two-terminal device, so the arrow is just laid diagonally across the middle. A potentiometer is a three-terminal device, so the arrow becomes the third terminal (the wiper).

The slide switches are also known as “single throw-double pole” (STDP) switches, because only one switch (or throw) exists, but two positions (or poles) are available (a pole is an electrical contact to which the switch can make contact). These switches can be set to output either Vdd (when the actuator is closest to the board’s edge) or GND. The push button switches are also known as “momentary” contact buttons, because they only make contact while they are actively being pressed – they output a GND at rest, and a Vdd only when they are being pressed. The figure below shows typically pushbutton and slide switch circuits used on Digilent boards.
