A typical television dissipates 275 W when it is plugged into a 120 V outlet. a). Find the resistance of the television. b). The television and 2.5 ohm wires connecting the outlet to the fuse form a series circuit that works like a voltage divider. Find the voltage drop across the television. c. A 12 ohm hair dryer is plugged into the same outlet. Find the equivalent resistance of the two appliances, (Hint, the hair dryer and television are connected in parallel). d). Find the voltage drop across the television and the hair dryer.
