Difference between One-Way Switch and Two-Way Switch
A switch is the most common device used in everyday life for turning on and off the electrical appliances. A switch can make or break a circuit. The electric current can flow in a circuit till the switch is in ON state. The switches are commonly used to turn on and off various electrical appliances like fans, lamps, coolers, ACs, etc.There are a number of switches available, but in this article, we will only discuss about the one-way switch and two-way switch and the key differences between the one-way switch and two-way switch.What is a One-Way Switch?A one-way switch is ...
Read MoreDifference between Isolator and Circuit Breaker
In electrical power system, various devices are used to ensure the safe operation of electrical equipment. The most important set of these devices that helps to ensure this safety is switchgears. Amongst these switchgears, the circuit breakers and isolators are commonly used in every electrical power system. These two devices are very important in an electrical power system.The isolator and circuit breaker both have a similar function of disconnecting the electrical circuits when there is an issue in electrical system. Therefore, they are closely related to each other, however, there are many differences between circuit breaker and isolator that draw ...
Read MoreDifference between Fuse and Circuit Breaker
An electric circuit is the interconnection of circuit elements which carries the electric power from the source to the load. Sometimes, the electric power (or voltage or current) in the circuit may increase suddenly, which cause damages of the load or other devices in the circuit. Therefore, in order to protect the electric circuit and appliances from getting damaged due to abnormalities in the circuit, two protecting devices viz. fuse and circuit breaker are used in the circuit.In this article, we will discuss about the differences between fuse and circuit breaker. Also, we will add a brief description of both ...
Read MoreDifference between Contactor and Relay
Contactor and relay are both electromagnetic switches that are designed to provide switching and controlling functions in the electric circuits. The primary function of both relay and contactor is similar, but there are many differences between them that are listed in the table below.The major difference between these two devices is that a relay is suitable for voltage and current applications, whereas a contactor is suitable for high voltage and current applications. Relays and contactors are both switches which are operated electrically for providing switching and controlling of the circuit.This article will provide all the noticeable differences between a contactor ...
Read MoreDifference 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 ...
