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…
From the diagram, the primary voltage is Vp = 2.10 V and the secondary voltage is Vs = 41.2 V Based on the given voltmeter readings, the number of turns and current through the primary and secondary coil can be found. The relationship is given below N subscript s over N subscript p equals V subscript s over V subscript p equals I subscript p over I subscript . How do they know which voltmeter measures primary voltage and which one measures secondary voltage?
