On which part of the power system, the occurrence of failure / abnormal condition is more?
On which part of the power system the occurrence of failure / abnormal condition is more? The probability of occurrence of failure / abnormal condition is more in the on the power line. The reason is nothing other than its length and operating conditions. It is highly affected by the weather conditions and other atmospheric … Read more
Working of Diode rectifiers (Uncontrolled rectifiers)
Introduction Circuits that are used to convert the Alternating Current (AC) input power into a Direct Current (DC) output power is known as rectifier circuits. Rectifiers are found in almost all equipment, from a low voltage battery charger to High Voltage DC transmission systems. Basically, rectifiers are classified into Controlled rectifiers and uncontrolled rectifiers. In … Read more
Comparision of conventional energy resources
Conventional energy is obtained from the conventional energy resources such as coal, diesel, gas and nucleus. These are non-renewable resources and may exhaust in few decades if consumed at the current rate. The burning of fossil fuels produces harmful gases such as nitrous oxide, carbon monoxide, sulphur-di-oxide etc and pollutes the environment. The comparison of various … Read more

What is inductance?
It is a property of a circuit element called inductor to store energy in the magnetic field when current passes through it. A basic inductor can be made by simply twisting a coil of a certain length. If current passes through an inductor, an electro magnetic field is formed. Any change in the magnitude … Read more
What is voltage?
There are two types of charges namely positive charge and negative charge. As we all know these charges are opposite and they attract . A work is done to separate these two charges through a specific distance. When these two charges are separated from each other certain amount of energy is stored in them in … Read more
