A uniform wire of resistance `R` is slaped into a regular n-sided polygon (n is seven). The equivalent resistance between any two corners can have :

Options

A. the maximum value` R//4`
B. the maximum value `R//n`
C. the value of equivalent resistance is `R((n-1)/n^2)`
D. the minimum value `R//n`

Explanation

To find the equivalent resistance between any two corners of a regular 7-sided polygon formed by a uniform wire of resistance \( R \), we can follow these steps:

### Step 1: Understand the Configuration
A regular 7-sided polygon (heptagon) has 7 vertices (corners) and can be thought of as having 7 equal segments of wire, each with a resistance of \( \frac{R}{7} \).

### Step 2: Identify the Resistance Between Two Corners
When considering the resistance between two adjacent corners (let's call them corner A and corner B), the wire segment directly connecting them has a resistance of \( \frac{R}{7} \).
