Internal Inductance Consider a long conductor carrying current “I” and having radius of conductor “r” as shown in figure below. According to Ampere’s law which states that the line integral of the magnetic field intensity (H) around a closed path (a closed loop or a closed curve) is equal to the total current (Ienc) passing through the enclosed surface. Let “Hx” is the magnetic field intensity…

Why Combinations of Capacitors Needed The use of combinations of capacitors is similar to the combination of cells (batteries) we use in everyday life. For example, if we need an 8V DC power supply and have four 2V electric cells, we can connect them in series to obtain the desired 8V supply. Capacitors work in a similar way. They allow us to store electrical energy by creating an electric field…

Why Size Selection of Electrical Power cables is Important ? In order to make sure that Electrical Power cables can function safely and handle a full load without getting damaged, it is crucial to perform cable sizing calculations. These calculations help us determine the right cable size to provide the appropriate voltage for the load.Additionally, proper sizing enables us to withstand the most…

In areas with high salinity levels, such as coastal regions or places exposed to salt-heavy environments, corrosion prevention is of utmost importance when it comes to lighting fixtures. The corrosive nature of salt can cause significant damage to these systems, leading to reduced performance, increased maintenance expenses, and a shorter lifespan. To ensure optimal functionality and longevity of…

Load Curve A load curve, also known as a chronological curve, is a graphical representation of the amount of power demand (measured in kW or MW) over a specific time period, typically in hours. It displays how the demand for power varies over time for a power station. When the load curve is plotted for a complete day, it’s known as a daily load curve, and when it’s plotted for a full year, it’s…

In a major breakthrough for the US renewable energy sector, a brand-new offshore wind farm is set to utilize some of the largest wind turbines in the world to generate electricity. These turbines are so large that just one rotation of the blades will provide enough power to a typical household for two whole days!

Introduction of Electrical Cables Electrical cables are a type of insulated wires that are used for transmitting electricity or electrical signals from one point to another. These cables are made up of two or more insulated conductors that are twisted or braided together to form a single cable. The conductors are usually made of copper or aluminum, which are good conductors of electricity. The…

Compensating Winding When generators need to supply a heavy current but have weak magnetic fields excitation, they need an auxiliary winding called a Compensating Winding. This winding helps to balance out the Cross magnetising effect of the armature reaction. It also helps to keep the magnetic field evenly distributed under the main poles.

Need of Combining of Resistances Combining resistances is a fundamental concept in electronics and circuit design. Resistors are used to limit current flow and voltage, and they can be combined in different ways to achieve different results. Here are some of the reasons why combining resistances is needed: To increase or decrease resistance: By combining resistors in series, you can increase…

A solar power plant are power plants that uses solar panels or mirrors to convert sunlight into electricity. The electricity can be used to power homes, businesses, and communities. There are several different types of solar power plants are as below Photovoltaic (PV) power plants: These use solar panels to convert sunlight into electricity. They can be built on a small scale, such as on the…

Mutual inductance | Formulae | Coefficient of Coupling | Units |

What is mutual inductance Mutual Inductance is the property of a coil to induce an emf in a nearby coil by principle of magnetic induction when the current in the first coil changes. The two coils should lie into close proximity with each other so the magnetic field from one links with the other. It is denoted by “M”. The S.I. unit of mutual inductance is Henry (H) Explanation of Mutual…
