In electrical engineering, a transformer is a static electrical machine which is employed for transforming the level of alternating voltage, i.e. for stepping-up and stepping down the voltage, for transmitting the electric power from generating station to utility points.The transformer changes the level of alternating voltage without changing its frequency. The transformer works on the principle mutual inductance. A typical transformer consists of two windings one is primary winding and the other is secondary winding. The input supply is connected to the primary winding of the transformer, while the transformed output is taken from the secondary winding, also the load ... Read More

In an AC electric circuit, when the capacitive reactance is balanced by the inductive reactance at some given frequency, then this condition in the circuit is referred as resonance. The frequency of the supply voltage at which resonance occurs in the circuit is called resonant frequency. At the resonance in the circuit, the reactance of the capacitor and inductor cancel each other. Also, at the condition of resonance, no reactive power is taken from the source.Based on the arrangement of capacitor and inductor in the electric circuit, the resonance is divided in two types viz. −Series resonanceParallel resonanceIn this article, we ...

In electric circuits, resistance (or resistor) is one of the elementary component. The resistors are connected in different fashion in an electric circuit, such as series,  parallel and series-parallel, etc.This article is meant for explaining the differences between combination of resistances in series and parallel. Also, we have briefly explained the series combination and parallel combination of resistances.Resistances in SeriesWhen two or more resistances are connected end to end, i.e. the ending terminal of one resistance is connected to starting terminal of second resistance, and the ending terminal of second resistance to the starting end of third resistance and so ...

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 More

Resistance and reactance are the two major parameters of an electric circuit element that together form the impedance of the circuit element. One most significant difference between resistance and reactance is that the resistance is the opposition in the flow of electric current offered by a circuit element called resistor, whereas the reactance is the opposition in the change in the magnitude and direction of the current and voltage offered by a circuit element called inductor or capacitor. The combined opposition offered by the resistance and reactance in an electric circuit is known as impedance of the circuit. In this ... Read More

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 ...

A rectifier is an electronic circuit that converts the alternating current (AC) into direct current (DC). The process of conversion of alternating current into direct current is known as rectification. The rectifier consists of semiconductor diodes to perform the rectification.Depending upon the type of conversion of AC into DC, i.e., half cycle of AC into DC or full cycle of AC into DC, the rectifiers are classified into two categories viz. −Half Wave RectifierFull Wave RectifierIn this article, we will discuss about the differences between half-wave rectifier and full-wave rectifier. Also, we will briefly discuss about the half-wave rectifier and ... Read More

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 ...

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 ...
