Voltage regulation is the process of holding a voltage steady under conditions of changing applied voltage and changing load current. Many electronic systems require a stable power supply voltage and use voltage regulators to accomplish that.

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across those two points. It means that more the resistance lesser current would flow. I=V/R This would apply to any component of a circuit. For example conductors would increase the current flow and the inductors would decrease it.

The circuits and components of a double-layer PCB board are usually connected in one of two ways: either utilizing a through-hole or with the use of a surface-mount. A through-hole connection means that small wires, known as leads, are fed through the holes, with each end of the leads then soldered to the right component.

The same current would flow through all the components while the voltage would differ from one component to another. For example you have lit three lamps in series to the same power source, the first one would receive more voltage than the last.

As the voltage applied between anode and cathode increases, forward current increases slowly at first, as charge carriers begin to cross the depletion layer then increasing rapidly in an approximately exponential manner. The resistance of the diode, when ‘turned on’ or conducting in a ‘forward biased’ mode is therefore not zero ohms, but is very low. Because forward conduction increases after the depletion potential is overcome in an approximately following exponential curve, forward resistance (V/I) varies slightly depending on the voltage applied.

The real part and imaginary part of impedance are interpreted as a resistive part that dissipates energy and a reactive part that stores energy. Resistors can only dissipate energy and therefore their impedances have only a real part. Capacitors and inductors can only store energy and therefore their impedances have only an imaginary part. When resistors, capacitors, and inductors are combined, the overall impedance may have both real and imaginary parts. It is important to note that the definition of impedance preserves the definition of resistance.

Many different types of components and devices can be found in modern circuits, including resistors, capacitors, and inductors, semiconductor devices like diodes, transistors, and integrated circuits, transducers like microphones, light sensors and motions sensors, actuators like motors and solenoids, and various other devices like heating and lighting elements. Devices in a circuit are connected to one another by means of electrical conductors, or wires. These wires can move electric currents between various points in a circuit. Once a wire connects two or more devices, the wire and all attached device connectors are said to form a single circuit node or net. Any electrical activity on a given net is communicated to all devices attached to the net. Certain nets provide electric power to devices, and other nets carry information between devices. Nets that carry information are called signals, and signals transport information encoded as voltage levels around a circuit. Signal nets typically use smaller conductors, and transport very small currents. Nets that carry power are called supply rails (or just supplies) and supply rails transport electric power around a circuit. Power nets typically use much larger conductors that signal nets, because they must transport larger currents.
