Hello guys, I hope you all are doing great. In today’s tutorial, we will have a look at the Difference Between Resistance and Reactance. In electrical circuitry, the reactance and resistance are the 2 main parameters that make impedance after coming with each other. The hindrance offered by the current flow in the resistor is called resistance. While reactance is a hindrance in flow of current through the inductor and capacitor.

In today’s post we will have a detailed look at both resistance and reactance parameters and compare them to find their differences. So let’s get started with Difference Between Resistance and Reactance.

Difference Between Resistance and Reactance

Resistance

• The opposition in flow of current through the resistor is called resistance.

• The resistance offered by the material depends on the larger portion that it has.
• The material created with the use of rubber offered a large value of resistance.
• the conductor has less value of resistance
• The material that offered the 0 resistance is called superconductor
• Its inverse value is electrical conductance.
• It has some features like to friction.
• Resistance value depends on the length of conductor and area
• larger length large resistance large area less resistance
• The unknit of conductance is siemens.
• It denoted with the R.

 

 

• Its formula is R=ρl/A.
• Resistance is exited in both AC and DC circuits.
• It is a real portion of impedance.
• Its value depends on the resistivity, dimension, and temperature of the conductor.
• For resistance the angle between volts and current is similar or there is no phase difference between them.
• Across resistor the part of net power losses.

What is Ohm’s Law

• According to Ohm law current passing in the substance has proportional relation with the voltage given to that object.

I∝ V

What is resistivity

• It is a feature of material through which current is passing and also called specific electrical resistance. The inverse of electrical resistivity is called electrical conductivity.
• The unit of resistivity ohm meter.

What is Ohmmeter

• The ohmmeter is a device that used to finds the value of resistance. There is another type of meter called megohmmeter that used to finds large value of resistance.
• Its measuring unit is ohm

Reactance

• The flow of current through the circuitry has an inductor or capacitor.
• A larger value of reactance caused to make less value of voltage given.
• Reactance is like resistance and has some differences that not lose power like resistance.
• Reactance is used to measure the amplitude and phase of ac.

• With the increment in frequency, there is an increment in inductive reactance
• It denoted as X.
• inductive reactance is a feature of the inductor and defines the current flow through the inductor
• It is an imaginary portion of impedance.
• Its formula for an inductor is XL=2ΠfL and for capacitor XC=1/2ΠfC.
• This term is only related to circuitry through which AC current is flowing.
• The circuit component for reactance is an inductor or capacitor.
• Its value depends on the frequency of AC current.
• For reactance, there is the phase difference between volts and current.
• For this element, some part of power given to the circuit is stored.

Resistance Vs Reactance

• There is the same behavior shown by resistance to reactance. The circuitry consists of reactance is works like the circuitry creates through zero value reactance.
• These two terms also have some difference that reactance varies the phase, therefore, the current in the component is moved through 1/4 of the cycle according to voltage given about the component.
• In pure reactive component, there is no power lost but saved in it. The value of reactance is negative

• .

That is all about the difference between resistance and reactance. If you have any query ask in comments. Soon I will upload the next interesting post. Thanks for reading. Have a good day.
