A conductor is an extreme case of a dielectric, because if an electric field is applied to a conductor, charges are free to move within the conductor to set up ''induced charges''. What is the dielectric constant of a perfect conductor? Is it `K=0,Krarroo`, or something in between ? Explain your reasoning.

Explanation

To determine the dielectric constant of a perfect conductor, we can follow these steps:

### Step 1: Understand the Concept of Dielectric Constant
The dielectric constant (K) of a material is defined as the ratio of the electric field in a vacuum (E₀) to the electric field in the material (E) when an external electric field is applied. Mathematically, it is expressed as:
\[ K = \frac{E_0}{E} \]

### Step 2: Analyze the Behavior of a Perfect Conductor
In a perfect conductor, when an external electric field is applied, the free charges within the conductor move in response to the field. This movement of charges creates an induced electric field that opposes the applied electric field, leading to a situation where the net electric field inside the conductor becomes zero.
