Question

Problem 26b

Answer 1

Given information

Given a source emf and asked to describe how the frequency of the source emf affects the impedance of a pure capacitance.

Step-by-step explanation

Step 1.

The impedance of a pure capacitance varies inversely with the frequency of the source emf.

 

We have, impedance of pure capacitance,

 

So when the source frequency is high, the impedance of the capacitor becomes small, and as the source frequency is small, the impedance of the capacitor becomes high.
