## Homework Statement

In the circuit shown below, a potentiometer is connected across the load resistor RL. The total resistance of the potentiometer is R = R1+R2 = 5 kΩ.

(a) Obtain an expression for the power PL dissipated in RL for any value of R1.

(b) Plot PL versus R1 over the full range made possible by the potentiometer’s wiper.

## Homework Equations

## The Attempt at a Solution

I don't understand if I need to find the thévenin resistance for this, also I don't know how to really start the problem and need a hint for finding the power for any value of R1
