So maybe I'm overthinking or something but here's the question:
Power outlet open-circuit voltage is measured at exactly 240V. The fan heater(rated at 240V and 2kW) is connected to outlet and voltage V drops to 236.4V. Find the Series resistance (Rs).
From the previous question I calculated the load resistance (Rl) to be 28.8ohms (V^2/P) - to which i checked the answers and is correct. However for Rs it's 04386 ohms and I have no idea how they got that.
Any help would be great.
