## bharatindians Group Title what is impedance ? @Physics 2 years ago 2 years ago

1. myjoytou Group Title

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

2. myjoytou Group Title

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

3. myjoytou Group Title

impedance is basically resistance of LCR circuit

4. abhishekes Group Title

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. estebananaya Group Title

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