What is the theory of circuits?

Theory

Theory of circuits is a set of used techniques describes the flow of energy around the electric loop. The theory consists of a number of different laws, ideas and definitions. These include Ohm's Law and Kirchhoff's Lawa, which describe the relationship between current, tension and resistance. In some cases, perimeter theory may also refer to hydraulic or pneumatic circuits that include fluid and gas. The electrical circuit is created using a range of components such as batteries, wires, capacitors, resistors and switches.

The electrical current at the microscopic level is the flow of electrons around the perimeter. Electrons are negatively charged particles. This is the basic reason why the "work", ie the name of the energy provided or carried out on the object in physics, can be transmitted by an electrical circuit. The theory of circuits is a collection of laws and techniques that allow people to design circuits for specific goals and purposes.

Any circuit is created by means of a components. These are called "active" components that give energy, and“Passive components” that use energy. In the case of electronic circuits theory, battery or generators are usually active components.

There are a number of passive electrical components that are important in the theory of circuits. The basic circuit "testing" usually consists of battery, passive components such as a lamp and a variable resistor. The variable resistor can be adjusted at any time, allowing the current over the component to change. Other components that are commonly used in electrical circuits include diodes that allow electricity flow in only one direction, and capacitors that can store electric charge and release if necessary.

The cornerstone of the theory is Ohm's law, which is a simple formula for developing the relationship between current, voltage and resistance in the circuit. The formula is written as "current equals the voltage divided by resistance". In other words, the resistance of the conductor is independent ofstream. This formula is often used in the theory of circuits to determine how much resistance it could be required to achieve a certain current level.

Kirchhoff's laws are also an important part of the theory of circuits. There are several laws, each describing the maintenance of energy and charge in the perimeter. Acts on protection of preservation are among the most important in physics as a whole, and Kirchhoff's laws use these general principles for electronic circuits.
