## anonymous 4 years ago what is impedance ? @Physics

• This Question is Closed
1. anonymous

impedance is a type of resistance to current flow and is given by where Xl is inductive reactance and Xc is capacitive reactance

2. anonymous

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

3. anonymous

impedance is basically resistance of LCR circuit

4. anonymous

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).

5. anonymous

Impedance is nothing but the voltage current ratio: $Z = V / I$
