Ans: D. The sum of the currents through each load
Question: what condition can cause a reduction from design capacity in a
heat pump?
Ans: A. An undersized vapor line
Question: What can happen if defrost runoff is not properly drained away?
Ans: B. Ice can build up on the bottom of the coil

Question: What effect does a low charge have on the switch over operations
of a reversing valve?
Ans: C. Reversing valves are less likely to shift if charge is very low
Question: The technician is using an analog multi meter to check a run
capacitor. With the meter set to OHMS the needle swings towards zero and
then slowly rise is toward infinity. What does this tell the technician about the
capacitor?
