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, 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 the 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 a superconductor
- Its inverse value is electrical conductance.
- It has some features like to friction.
- The resistance value depends on the length of the conductor and the area
- larger length large resistance large area less resistance
- The unknit of conductance is Siemens.
- It is 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 is used to find the value of resistance. There is another type of meter called a megohmmeter that is used to find large values 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 is 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 a 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 a phase difference between volts and current.
- For this element, some part of the 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 differences in that reactance varies the phase, therefore, the current in the component is moved through 1/4 of the cycle according to the voltage given about the component.
- In pure reactive component, there is no power lost but saved in it. The value of reactance is negative
