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 wasted in transmission cables and how to reduce it, we can follow these steps:

### Step 1: Understand the Power Delivered
The power `P` is delivered to a device through transmission cables with resistance `R_c`. The relationship between power, voltage, and current is given by the formula:
\[ P = V \times I \]
where `V` is the voltage across the device and `I` is the current flowing through it.

### Step 2: Calculate the Current
