Required information The diagram shows a simplified household circuit. Resistor R1: 329.0 Q represents a lightbulb; resistor R2 = 23.0 0 represents a hair dryer. The resistors r= 0.500 O (each) represent the resistance of the wiring in the walls. Assume that the generator supplies a constant 120.0 V rms. H0! The lightbulb is initially on and the hair dryer is off. How much does the rms voltage across the lightbulb decrease when the hair dryer is switched on? (Give the magnitude of the decreaseLe, a positive answer.)
