A) zero
B) infinity
C) \[1\Omega \]
D) \[\frac{1}{2}\,\,\Omega \]
Correct Answer: B
Solution :
Capacitive reactance \[({{X}_{C}})\]is given by \[{{X}_{C}}=\frac{1}{\omega C}\] where \[\omega \] is angular frequency and C the capacitance. Also, \[\omega =2\pi f,\] where f is frequency. In a DC circuit \[f=0\] \[\therefore \]\[\omega =0\] \[{{X}_{C}}=\frac{1}{0}=\infty \]
