A transformer steps up an alternating current from
12V to 144V. If the current in the primary coil is 2A.
calculate:
(a) the electrical power of the primary coil
coils
answer = W
(b) the current in the secondary coil
(assuming a 100% efficient transformer)
answer = A

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
