(a) Find the power POA absorbed by an unloaded 741 op amp powered from 615-V supplies and with the output near 0 V. Hence, verify that the sum of the power released by the supplies equals that absorbed by the op amp. (b) Find POA if the op amp is sourcing to the surrounding circuit a current of IO 5 2 mA at VO 5 10 V. Again, verify the conservation of power. (c) Repeat (b) if the op amp is sinking from the surrounding circuit a current of IO 5 1.5 mA at VO 5 28 V.
