Question

Compare resistance and reactance.

Answer 1

Comparison between resistance and reactance:

Resistance	Reactance
1. A circuit's opposition to current flow is measured by its resistance.	1. Reactance is a type of resistance to the flow of alternating current (alternating current) that electronic components exhibit as a result of capacitance or inductance.
2. $\mathrm{R}$ is used to denote resistance.	2. $\mathrm{X}$ is used to denote reactance.
3. $\mathrm{R}=\frac{\mathrm{V}}{\mathrm{I}}$ $\mathrm{V}$ is voltage and $\mathrm{I}$ is current.	3. $\mathrm{X}={\mathrm{X}}_{\mathrm{L}}=2\mathrm{\pi fL}$ and ${\mathrm{X}}_{\mathrm{C}}=\frac{1}{2\mathrm{\pi fC}}$ $\mathrm{f}$ is frequency. $\mathrm{L}$ is inductance. $\mathrm{C}$ is capacitance.
4. Voltage and current are in the same phase.	4. The phase difference is $90$ between voltage and current.
