# 14 Difference Between Resistance and Impedance

In an earlier tutorials, we have learned the two main differences like-

In this post, we are going to study what is difference between resistance and impedance.

### Resistance vs Impedance in Tubular Form

#### 13. Symbollc representation of Resistance and Impedance

• Resistance (R) Symbol:
• Impedance (Z) Symbol:

#### 14. Formula of Resistance and Impedance

• Resistance Formula
`Resistance (R)  = (Voltage / Current)                        (Unit- Ohm)   `
• Impedance Formula
`Impedance (Z) = [√(R2 + X2)] = [√R2 + (XL-XC)2]        (Unit- Ohm)   `

Where, XL is inductive impedance and XC is capacitive impedance.

These are the 14 basic points of comparisons between resistance and impedance with the help of basic concepts, symbolic representation, and their formula.

The similarity in between the resistance and impedance is a unit. Both has same unit i.e. Ohm (Ω)
