Question

at very high frequency of AC ,capacitor behaves as conductor.why?

Answer 1

Answer:

Xc=1/2πfC , Xc is inversely proportional to frequency

Explanation:

Hence at very high frequency, capacitive reactance becomes negligibly small and capacitor behaves like a conductor

Answer 2

Question:

At very high frequency of AC ,capacitor behaves as conductor.Why?

Answer and explanation:

The reactance of a capacitor is Xc=  1 /2πfC, where f is the frequency of AC supply and C is the capacitance of the capacitor.Resistance of the capacitor is inversely proportional to the frequency of the electric signal.For very high frequency, f, Xc becomes very small(negligible) . As a result, whenever any component offers zero resistance to an electric signal it behaves like a conductor. At a very high-frequency AC supply, the capacitor behaves like a pure conductor.

(Xc's c would be in subscript form.)
