B) The condensate from a furnace is mildly acidic and can damage the materials in some condensate pumps.
C) The condensate from a furnace is mildly alkaline and can damage the materials in some condensate pumps.
D) The furnace manufacturer will void the warranty if the wrong condensate pump is used.

Fill in the blank(s) with the appropriate word(s).
Find v1 in the circuits of Figure P8.5(a) and (b). In Figure P8.5(a) the 3-k? resistor “loads” the output; that is, v1 is changed by attaching the 3-k? resistor in parallel with the lower 6-k? resistor. However, in Figure P8.5(b) the isolation buffer holds v1 to vg/2, regardless of the presence of the 3-k? resistor and its value!
