(a) The figure below depicts a 0-to-10 kn potentiometer as a variable load resistor RL connected to a circuit of an unknown architecture. When the wiper position on the potentiometer was adjusted such that RL = 1.2k2, the current through it was measured to be 3 mA, and when the wiper was lowered so that R₁ = 2k2, the current decreased to 2.5 mA. Determine the value of RL that would extract maximum power from the circuit.

KVL and KCL
KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.
Sign Convention
Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.
Question
We were studying Thevenin first and then from those concepts we were solving for power. Could you help me betterunderstand step by step the track of thought?
Thank you so much! :)
