Ayoung man owns a canister vacuum cleaner marked "533 w [at] 220 v" and a volkswagen beetle, which he wishes to clean. he parks the car in his apartment parking lot and uses an inexpensive extension cord 19.0 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 0.500 ω what is the actual power delivered to the cleaner?

(b) if instead the power is to be at least 523 w, what must be the diameter of each of two identical copper conductors in the cord he buys? (enter the minimum diameter.)

(c) repeat part (b) assuming the power is to be at least 530 w. (enter the minimum diameter.)
