Power `P` is to be delivered to a device via transmission cables having resistance `R_(c)`. If `V` is the voltage across `R` and `I` the current through it , find the power wasted and how can it be reduced.

Explanation

To solve the problem of power wastage in transmission cables, let's break it down step by step.

### Step 1: Understanding Power in Transmission Lines
The power wasted in the transmission lines can be expressed using the formula:
\[ P_{\text{wasted}} = I^2 R_c \]
where:
- \( P_{\text{wasted}} \) is the power wasted in the transmission cables,
- \( I \) is the current flowing through the cables,
