Question

A capacitor is connected to an AC supply. Increasing the frequency of the supply..........the current through the capacitor

A. does not change
B. increases
C. decreases

Answer 1

B. increases

Step-by-step explanation:

As the frequency of the AC supply increases, the

The current through a capacitor increases as the frequency of the supply increases. This is because the capacitor's reactance decreases with increasing frequency. The reactance of a capacitor is inversely proportional to the frequency of the supply. Therefore, as the frequency increases, the reactance decreases and the current increases.

Here is a graph that shows the relationship between the current through a capacitor and the frequency of the supply: Attachment

The graph shows that the current through a capacitor increases as the frequency of the supply increases. This is because the capacitor's reactance decreases with increasing frequency. The reactance of a capacitor is inversely proportional to the frequency of the supply. Therefore, as the frequency increases, the reactance decreases and the current increases.
