Imagine that you wanted to utilize a voltage divider to provide an RMS AC output voltage of 10V using a typical 120V (RMS) US household wall socket as the input. For this situation write down a simple mathematical relationship relating the resistance values of the two resistors R1 and R2 that you would use in your circuit.
