How will displacement current between the plates of a parallel connected to a variable frequency AC source change with increase in the frequency of the source .

Explanation

To determine how the displacement current between the plates of a parallel plate capacitor connected to a variable frequency AC source changes with an increase in the frequency of the source, we can follow these steps:

### Step 1: Understand the Concept of Displacement Current
Displacement current is a concept introduced by James Clerk Maxwell to account for the changing electric field in a capacitor when an alternating current (AC) flows through it. It is given by the formula:
\[ I_D = \epsilon_0 \frac{d\Phi_E}{dt} \]
where \( \Phi_E \) is the electric flux and \( \epsilon_0 \) is the permittivity of free space.
