A set of 'n' identical resistors, each of resistance 'R' when connected in series have an effective resistance 'X'. When they are connected in parallel, their effective becomes 'Y'. Find out the product of X and Y.

Explanation

To solve the problem, we need to find the effective resistance when 'n' identical resistors, each of resistance 'R', are connected in series and in parallel, and then calculate the product of these two effective resistances.

### Step-by-Step Solution:

1. **Effective Resistance in Series (X)**:
- When 'n' identical resistors are connected in series, the total or effective resistance \(X\) is the sum of the individual resistances.
- Formula:
\[
