An unknown resistor is connected to an AC voltage source as shown. The rms source voltage is controlled by the slider. You can click-drag inside the graph to measure coordinates and place the mouse on a circuit component to obtain readings.
Find the unknown resistance if current is measured in milliamperes, mA. Start
500 W.
