A real voltage source provides 1.5 V and has an internal resistance of 2 Ohm. Which of the following circuits would store more energy when connected to that source? Two capacitors C1=1mF and C2=3mF in series Two capacitors C1=1mF and C2=3mF in parallel Two inductors L1=2mH and L2=3mH in series Two inductors L1=2mH and L2=3mH in parallel All of the above would store the same power when connected to the source

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
