Most household power in North America is 120? alternating current (VAC). However, some high-power appliances such as electric ranges and clothes dryers typically require a special 220?circuit. In this problem, you will calculate the energy, power, and current required by a dryer. You will also compare different methods of storing the energy required to run this appliance in a typical drying cycle. Consider a dryer that operates on 220?electricity, and it consumes an average power of 3000?. For this homework, the “Alternating Current” part of the story is irrelevant, so please use our ordinary DC equations (Perhaps this dryer has been specially made for physics experiments so it has a second input that allows it to operate on DC voltage as well!) A cubic meter of “natural gas” (mostly methane) at atmospheric pressure contains about40?? of usable energy. How much natural gas (in m3) would it take to power the dryer for 30minutes? Do some googling, and make an estimate (that means getting…
A power plant produces a voltage of 6.0 kV and 150 A. The voltage is stepped up to 250 kV by a transformer before it is transmitted to a substation. What is the current in the transmission line from the plant to the substation?
Suppose a large power plant generates electricity at 12.0 kV. Its old transformer once converted this voltage to 325 kV. The secondary coil of this transformer is being replaced so that its output can be 755 kV for more efficient cross-country transmission on upgraded transmission lines. V1= 325 kV V,= 755 kV (a) If the overall power output is 1000.0 MW and line resistance is 2.00 N, what was the power loss, in watts, in the old power lines which left the plant?

A 1·21-MF Capacitor is connected to a North American electrical outlet. (AVrms = 120V₁ f = 60.0Hz). Assuming the energy stored in the Capacitor is Zero at + = 0, determine the magnitude & the current in the wires at t = 192 Note: Answer must be in A. S.
You decide to “go green" and use an exercise bike to power your home appliances. Assume that your exercise bike is rigged to generate electrical power with 60% efficiency. In other words, only 6/10 of the power you develop can be used to store electrical energy for later use. Consider your 3500-Watt central AC unit. You need to run this unit for 4 hours each day during the summer. If you can develop a sustained power of 300 Watts on your exercise bike, how long would you have to work out just to keep the AC running on a summer day?
