What happens when vp>> vn? When vn>>vp?
Consider the Op-Amp circuit in the open loop configuration. The general curve for is shown to the right. Typically Op-Amps have very high open loop gain so their linear region is pretty small. This can make them very useful for detecting when vo > Vn and vice versa. (Hmmm I wonder if this could be helpful for the night light circuit design). Positive saturation region + | ooo Negative saturation region +-- Linear...

Which of the following statements is true regarding an ammeter? Ammeters have a very high resistance and are placed in parallel with a resistor. Ammeters have a very high resistance and are placed in series with a resistor. Ammeters have a very low resistance and are placed in series with a resistor. Ammeters have a very low resistance and are placed in parallel with a resistor.

1) The resistances of commercially-available discrete resistors are restricted to particular sets. For example, the available values of resistors with 10% tolerance are selections from the E12 set multiplied by a power of ten from 100 through 10s. The E12 set is: E12-10,12, 15, 18,22,27,33,39,47,56,68, 82) Thus, you can buy 10% resistors with a nominal resistance of 3300 or 33M. but not 350n. Furthermore, the tolerance a 10%...

Question 3 3 pts Focus on Op-amp U1 (Both op-amps have to be completely connected as shown in Figure A) Use myDAQ's oscilloscope to capture the input waveform Vin (on Channel 0) and the intermediate output waveform Vout1 (on Channel 1) superimposed. Set the amplitude scale for both channels of the oscilloscope to 500 mV/Div Set the time scale of the oscilloscope to 200 us/Div 1. Take a screenshot of the oscilloscope (both waveform in the same picture) and embed...

Why are high-rise buildings typically constructed in cities rather than in rural areas? O Land and capital are substituted for labor. O Labor and capital are substituted for land, which is very expensive. O Labor and capital are substituted for land because they are inexpensive. O Land and labor are substituted for capital.

2.[1pt Electrical power is typically transmitted over long distances at very high voltage, up to 1000 kV (for reasons that we will explore in the next problem). Suppose that bird a lands on a power line carrying 2690A, as seen in the figure below If the line has 3.08x10Ohm resistance per meter and the bird's feet are 3.60cm apart, what is the magnitude of the potential difference between the bird's feet? Answer: Incorrect, tries 2/6 Hint: Simple enough to calculate...
