An ideal transformer has a primary with 30 turns and secondary with 12 turns. The load resistor is 61 Ω and the source voltage is 88 Vrms . 88 Vrms RS 30 turns 12 turns 61 Ω If a voltmeter across the load measures 12.3 Vrms , what is the source resistance RS? Answer in units of Ω.

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
