A) 50
B) 250
C) 1250
D) 6250
Correct Answer: B
Solution :
The impedance of a series L-C-R circuit is given by \[Z=\sqrt{{{R}^{2}}+{{({{X}_{L}}-{{X}_{C}})}^{2}}}\] where \[{{X}_{L}}\] is inductive reactance and \[{{X}_{C}}\] the capacitive reactance. Given, \[{{X}_{L}}={{X}_{C}}\] \[\therefore \] \[Z=R=25\,\Omega \]You need to login to perform this action.
