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 \[f=0,\] \[\therefore \] \[\omega =0\] \[{{X}_{C}}=\frac{1}{0}=\infty \]You need to login to perform this action.
