Unformatted text preview: Jessica Ann Elrod- PHY 232 Spring 2007 1 Set 03 (01/30 midnight) Due date: Tue Jan 30 23:59:00 2007 The compressor of an air conditioner draws an electric current of 17.2 A when it starts up. If the start-up time is 1.45 s long, then how much electric charge passes through the circuit during this period? Tries 0/12 If 22.6 g of gold is deposited on the negative electrode of an electrolytic cell in a period of 2.25 hours, then what is the current through the cell during this period? (Assume that the gold ions carry one elementary unit of positive charge and the atomic mass of gold is 197.0 g/mol.) Tries 0/12 A person notices a mild electric shock if the current along a path through the thumb and the index finger exceeds 80.0 A. Calculate the maximum allowable voltage without shock across the thumb and the index finger with a dry-skin resis- tance of 4 . 05 10 5 . Tries 0/12 Calculate the maximum allowable voltage with a wet-skin resistance of 1440 . Tries 0/12 Calculate the diameter of a 2.23 cm long tungsten filament in a lightbulb if its resistance is 0.591 . (The resistivity of tungsten is 5 . 60 10...
