EMF and Voltage are the two fundamental aspects of electrical and electronics engineering. They may appear as same, but they are different electrical quantities. In order to understand the difference between EMF and voltage, we first need to understand their meaning.What is EMF?EMF stands for Electromotive Force. The measure of energy the power source (ex. Battery) gives to each Coulomb of charge is known as EMF of the power source or battery. The EMF is denoted by letter ‘E’. The SI unit of EMF is the same as the voltage, which is Volts.The EMF is the factor which creates and ... Read More

The Magnetomotive force (MMF) in a magnetic circuit is analogous to the electromotive force (EMF) in an electric circuit. MMF is the factor responsible for driving the magnetic flux in a magnetic core, while the electromotive force EMF is the factor responsible for the flow of electric charge (or electrons) in an electric circuit.What is Electromotive Force (EMF)?The total amount of energy given to a unit charge by a source of energy such as generator, battery, etc. is known as electromotive force (or EMF) of the energy source. As the electromotive force has “force” in its name but technically, the ... Read More

There is a property of space which is caused by the motion of the electric charge, is known as electromagnetic field. There are two component of an electromagnetic field viz. −Electric fieldMagnetic fieldA stationary electric charge produces only an electric field in the surrounding space. If the electric charge is moving, then it also produces a magnetic field. The electric field and magnetic field occupy different planes relative to the cause of the electromagnetic field, i.e., moving charge.Therefore, one of the major difference between electric field and the magnetic field is that the electric field produces around a static electric ...

In electrical and electronics engineering, regulating and controlling of the electric power delivered to the load is very important to reduce the wastage of electrical energy. This can be achieved by using DIAC and TRIAC which are two different types of power semiconductor devices.DIAC and TRIAC are used to control the AC power supplied to the load. Both DIAC and TRIAC can operate at high voltages and currents. Both these devices belong to the thyristor family, having p-n-p-n structure. But, DIAC and TRIAC are also different from each other in many ways. Read through this article to find out the ... Read More

Both conduction and convection are modes of heat transfer from one system to another. When there is a difference in the temperature of two systems, then the transfer of heat takes place from the system of higher temperature to the system of lower temperature.In practice, this transfer of heat takes place in three different modes viz. conduction, convection and radiation. But, in this article, we will only discuss about conduction and convection and how they are different from each other.What is Conduction of Heat?When the transfer of heat takes place from one part of the substance to another part without ...

A circuit is a type of network having a closed path for the flow of either electric current or magnetic flux. A circuit mainly consists of three major parts viz. source, path or conductor and load. In simple words, the term circuit can be used to represent any fixed path through which electricity, data, single or magnetic flux can flow.Depending on the type of quantity (electric current or magnetic flux), the circuits can be of two types as −Electric circuitMagnetic circuitIn this article, we are going to see the differences between electric circuit and magnetic circuit. Also, we have added ... Read More

The rate of work done in an electric circuit is known as electric power. In an electric circuit, there are three types of electric powers viz. active power, reactive power and apparent power. In this article, we will discuss the major differences between active power and reactive power. What is Active Power? In an AC or DC electric circuit, the amount of electric power which is utilized and consumed in doing a work is called active power. Active power is also known as real power or true power. Active power is usually represented by the letter ‘P’ and is ... Read More
