A) maximum
B) minimum
C) zero
D) infinity
Correct Answer: B
Solution :
(b) minimum At resonance frequency, the inductive and capacitive reactance are equal. \[\therefore {{X}_{L}}={{X}_{C}}\] Impedance, \[Z=\sqrt{{{R}^{2}}+{{\left( {{X}_{L}}-{{X}_{C}} \right)}^{2}}}=\sqrt{{{R}^{2}}+{{0}^{2}}}=R\]You need to login to perform this action.
