Most household power in North America is 120 V alternating current (VAC). However, some high-power appliances such as electric ranges and clothes dryers typically require a special 220 V circuit. Consider a dryer that operates on 220 Velectricity, and it consumes an average power of 3000 W (we can ignore the fact that this is "Alternating Current" for the time beingwe're just looking at the averages). 1. Most of the power consumed by the dryer goes into producing heat. Dryers have a \"heating element" which is along coil of wire and can be treated as a single resistor. Using the value of power, and the operating voltage, calculate this resistance. (2 points). What is the average current drawn by the dryer? (2 points) A USB port can be used as a S V, 500 mA DC power supply. How many USB ports would it take to produce 3000 W? (2 points) A cubic meter of \"natural gas" (mostly methane) at atmospheric pressure contains about 40 M] of usable energy. How much natural gas (in m3) would it take to power the dryer for 30 minutes? Do some googling, and make a rough estimate (just try to be within a factor of 10) of how much this much natural gas would cost you to buy.(2 points)
