Question

Statement A: At resonance of LCR series circuit, the reactance of circuit is minimum.
Statement B:The reactance of a capacitor in an A.C circuit is similar to the resistance of a capacitor in a D.C. circuit

• A. A is true but B is false
• B. Both A and B are true
• C. A is false but B is true
• D. Both A and B are false

Answer 1

The correct option is A A is true but B is false

$Z=\sqrt{R^2+(Z_L-Z_C{)}^2}$

at $w=\frac{1}{\sqrt{LC}}$

min $Z=R$.
