1.  2. What is a key feature of the inverting amplifier?
That both the input signals and the feedback are applied at the inverting terminal of the op amp
3. For an ideal op amp the voltages and current are?
Voltages: V1 = V2

Current: I1 = I2 == 0
4. An inverting amplifier ________ the polarity of the input signal while __________ it.
Reverses

Amplifying
5. The voltage gain of a inverter is?
Av = Vo/Vin = -Rf/R1

Vo = (-Rf/R1)(Vin)
6. If the gain is the Rf/R1 the gain depends only on the
external elements connected to the op amp
7. The inverting amplifier is used, for example, in a _______ converter
Current-to-Voltage
8. input voltage is applied directly to the noninverting input
and resistor is conected between the ground and inverting terminal.
What type of Amplifier
Noninverting Amplifier
9. The voltage gain of a noninverter is?
Av = Vo/Vin = (1+Rf/R1)

Vo = (1+Rf/R1)(Vin)
10. An noninverting amplifier is an op amp circuit designed to provide a _______ voltage gain
Positive
11. On a noninverting amplifier If the feerback resistor Rf = ___ Or R1 = ____ Or Both the gain becomes 1.
Rf = 0 (short circuit)

R1 = infinity (open circuit)
