Difference between Resistance and Resistivity
Resistance and resistivity are the major terms associated with the opposition in the flow of electric current in a circuit. The most significant difference between resistance and resistivity is that resistance is the measure of opposition offered by the material in the path of electric current, whereas resistivity is the property of material by virtue of which it opposes the electric current.In this article, we have explained all the significant differences between the resistance and resistivity in detail. Also, we have added a short description of resistance and resistivity for the reference of reader.What is Resistance?Electrical resistance is defined as ...
Read MoreDifference between Multimeter and Clamp Meter
Both multimeter and clamp meter are types of electronic measuring and testing instruments used to measure different types electrical quantities such as current, voltage, resistance, etc. However, these two devices test different electrical measurements. It is difficult to find out which instrument to choose for a specific measurement, especially if one is new to electrical work. But, in simple words, we can say that a multimeter is used to measure current, voltage, resistance, continuity, etc. while the clamp meter is used to measure currents.In this article, we have explained the differences between the multimeter and clamp meter along with their ...
Read MoreDifference between Converter and Inverter
Converter and inverter are both two important power-electronic devices in the field of electrical and electronics engineering. Inverters and converters are used for the conversion of AC power into DC power and vice-versa which is a very important phenomenon in the field power electronic engineering as well as in our day-to-day life.The most significant difference between these two devices is that a converter is a power-electronic device which can transform the electric power from one form (AC or DC) to another form (AC or DC), while an inverter is a type of power electronic converter which converters DC power into ...
Read MoreDifference between Centre-Tapped Rectifier and Bridge Rectifier
The electronic circuit which is used to convert alternating current (AC) into direct current (DC) is known as a rectifier. The process of converting the alternating current into direct current is called rectification. The main component of the rectifier which performs the rectification is the semiconductor diode.Depending upon the type of conversion from AC to DC, i.e. half cycle of AC or full cycle of AC, rectifiers can be grouped into two categories −Half-wave rectifierFull-wave rectifierBased on the circuit configuration, the full-wave rectifier is further classified into two types viz. −Centre-tapped full-wave rectifierBridge rectifierThus, both centre-tapped and bridge rectifiers are ...
Read MoreDifference between Apparent Power and Real Power
In an electric circuit, the rate at which the work is being done (or the energy is being expended) is known as electric power. Mathematically, electric power can be defined as the work done (or energy expended) per unit time, i.e., $$\mathrm{Power, \mathit{P}\:=\:\frac{Work\:done\:(\mathit{W})}{Time(\mathit{t})}}$$The unit of electric power is Joules per second.Based on the type of current, the electric power can be of two types viz.: DC power and AC power. The AC power is further classified into three main types as −Apparent power (S)Active power (P)Reactive power (Q)In this article, we will discuss about what the apparent power and the ...
Read MoreDifference between Ammeter and Galvanometer
Ammeter and galvanometer are both measuring instruments used to measure the current flowing through a circuit. The most significant difference between a galvanometer and an ammeter is that the ammeter measures only the magnitude of the current flowing in the circuit, while the galvanometer shows both magnitude and direction of the current in the circuit.Go through this article to know more about ammeter and galvanometer and the key differences between these two measuring instruments.What is a Galvanometer?A galvanometer is an electromechanical measuring device used to measure the strength of current and direction in an electric circuit. A typical galvanometer consists ...
Read MoreDifference between Electromotive Force (EMF) and Magnetomotive Force (MMF)
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 MoreDifference between Inverter and UPS
There are two important devices viz. UPS and inverter that are used extensively to provide backup supply to the electrical systems. As we know, today electricity has become a necessity because almost all of our day-to-day activities require electricity. Since, all the device such as mobiles, laptops, PCs, washing machines, coolers, ACs, etc. use electricity to work. If the electric supply gets down, it will greatly affect the operation of these devices. Therefore, to smoothly run these devices even after the cut out of electric supply, two electric power systems are designed named Inverter and UPS.Basically, both UPS and inverter ...
Read MoreDifference between P-N Junction Diode and Zener Diode
Both the PN junction diode and the Zener diode are semiconductor devices that are extensively used in various electronic circuits. A PN junction diode is mainly used for rectification (transforming AC into DC), while a Zener diode is used for voltage regulation in the electronic circuits.There are a number of differences in both PN junction diode and Zener diode which are explained in detail in the below table. Before going into the discussion about the differences between PN junction diode and Zener diode, it is fruitful to get the basic details about the PN junction diode and Zener diode.What is ...
Read MoreDifference between Permanent Magnet and Electromagnet
A magnet is a material or object which has ability to produce a magnetic field and can attract or repel other ferromagnetic materials. Based on the method of production of magnetic field, the magnets are classified into two types viz. −Permanent magnetElectromagnetThe main difference between an electromagnet and a permanent magnet is that an electromagnet produces the magnetic field by the effect of electric current flowing through a coil insulated wire wound around a piece of soft magnetic material. Whereas, a permanent magnet is made up of hard magnetic material and once it is magnetized, it can produce the magnetic ...
