Electric current Electric current is one of the most basic term in electrical engineering. It is the flow of electric charge in a closed circuit. In simple, when the valence electrons of a conductor start moving in the same direction the current is said to be flow through that conductor. Actually electric current define the rate of […]

Electrical Fuse
What is fuse? A fuse is piece of metallic wire generally connected in series with the load and protect circuit during faulty condition. It is made of material having low melting point. What is the function of fuse? The main purpose of fuse in an electric circuit is to give protection against short circuit and […]
Electrical energy
Electrical energy Electrical energy and electric power are closely related to each other. Electric energy do the use full work in electric circuit and can be transferred from source to load. Most of the time electric energy is defined as the product of electric power and time. But the right way of defining electrical energy is […]
EMF or Electromotive Force
Before introducing the topic I recommend you to read our earlier post on electric potential difference. Electromotive force or emf defined as the voltage generated by a source when circuit is open. It is the potential difference between two terminal of electric source when circuit is open. Suppose a resistor is connected across the terminal of a […]
Electric Faults
Electrical Faults The electric energy or power is transmitted and distributed from various generating station to load end. There are various fault which may occur in power system during transmission and distribution of electrical energy. Under Normal Condition, the electrical circuit or device operates at normal voltage and current, once the fault take place the […]
Ten Important things about transformer
10 things about transformer 1. Transformer is a static device which is generally used to change the voltage level of power system without changing its power and frequency. The main purpose of using transformer is to either increase or decrease the voltage level. The input side of transformer is called primary side and output side of […]
