For this quiz, ic = 0.2ma. treat the capacitors like ac short circuits and dc open circuits. rsig = 10kω, rc = 24kω, rl = 10kω va is large, so you can neglect go. the signal source is directly coupled to the base, so rb can be eliminated (rb≈∞) show your work and be careful with units.

As shown in fig. p3.64, a closed, rigid tank fitted with a fine-wire electric resistor is filled with refrigerant 22, initially at 2108c, a quality of 80%, and a volume of 0.01 m3. a 12-volt battery provides a 5-amp current to the resistor for 5 minutes. if the final temperature of the refrigerant is 408c, determine the heat transfer, in kj, from the refrigerant.

Which best represents the law of conservation of mass ?
