A linear power supply consists of a transformer, 4-diode bridge rectifier, smoothing capacitor, and a linear voltage regulator. The regulator has a 65 dB ripple rejection ratio. The ripple voltage across the smoothing capacitor is 350 mV. Which of the following is the best estimate of the ripple voltage across the load? a. About 0.11 HV.
b. About 200 μν.
c. About 5.4 mV
d. Need more information.

1kg of water contained in a piston-cylinder assembly undergoes two processes in series from an initial state where the pressure is 3.0 bar and the temperature is 150°c process 1-2: the water is compressed isothermally to a volume of 0.25 m^3 with 120 kj of work being done to the system. process 2-3: the water is heated at constant volume to a final pressure of 10 bar. a. find the change in internal energy for the system. b. calculate the amount of heat transferred, in kj. c. sketch both processes on a t-v diagram.
