Assertion: Capacitance serves as a block for `DC` and offerse an easy path to `AC`. Reason: Capacitance reactance is inversely proportional to frequency.A. If both the assertion and reason are true and reason is a true explantion of the assertion.B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.C. If the assertion is true but reason falseD. If both the assertion and reason are false. |
Answer» Correct Answer - A The capacitive reactance of capacitor is given by `X_(C)=1/(omega C)=1/(2pi f C)` So this is infinite for `DC (f=0)` and has a very small value of `AC`, therefore a capacitor blocks `DC`. |
