A young man owns a canister vacuum cleaner marked 535W at 120V and a Volkswagen Beetle, which he wishes to clean. he parks the car in his apartment parking lot and uses an inexpensive extension cord 15 m long to plug in the vacuum cleaner. you may assume the cleaner has constant resistance.
(a) if the resistance of each of the two conductors in the extension cord is 0.900?, what is the actual power delivered to the cleaner?
(b) if instead the power is to be at least 525W, what must be the diameter of each of the two identical copper conductors in the cord he buys (c) repeat part (b) asuming the power is to be at least 532W.
