Question

what is impedance ? @Physics

Answer 1

impedance is a type of resistance to current flow and is given by




where Xl is inductive reactance and Xc is capacitive reactance

Answer 2

\[Z =\sqrt{R ^{2}+(X _{l}^{2}+X _{c}^{2})}\]

Answer 3

impedance is basically resistance of LCR circuit

Answer 4

Impedance is a general term. In electrical engg. impedance is the property of the system(ckt) which is nothing but the measurement of opposition to electrical current when ckt is exposed to an excitation(voltage).

Answer 5

Impedance is nothing but the voltage current ratio:
\[Z = V / I\]
