## Understanding Electrical Networks in Electrical Engineering

Understanding Electrical Networks in Electrical Engineering Electrical circuits may consist of one or more sources of energy and number of electrical parameters, connected in different ways. The different electrical parameters or elements are resistors, capacitors and inductors. The combination of such elements along with various sources of energy gives rise to complicated electrical circuits, generally referred to as electrical networks. The terms circuit and network are used synonymously in the electrical literature. The dc circuits consist of only resistances and [...]

## Understanding Circuit Laws and Circuit Analysis in Electrical Engineering

Understanding Circuit Laws and Circuit Analysis in Electrical Engineering Circuit laws Two important laws are based on the physical properties of electric charges and these laws form the foundation of circuit analysis. They are Kirchhoff’s current law and Kirchhoff’s voltage law. While Kirchhoff’s Current Law (KCL) is based on the principle of conservation of electric charge, Kirchhoff’s Voltage Law (KVL) is based on the principle of energy conservation. Kirchhoff’s Current Law At any instant, the algebraic sum of the currents i entering a [...]

## Understanding Electric Charge in Electrical Engineering

Electric Charge The International System Unit of charge: C (Coulomb) Electricity is based upon the existence of electric charges, which are positive and negative. A force exists between electric charges, which is described by Coulomb’s law. Like charges repel each other and unlike charges attract each other. From the physical point of view, every charge is a multiple of the elementary charge e. Elementary charge e ­ ±1.602 × 10-19 Coulomb Electrons carry a negative charge and Protons carry a positive charge. A lack [...]
