Which of the below stated condition/s is applicable for Non-inverting amplifier?
A. Output Voltage is greater than input voltage
B. Output voltage is lesser than input voltage
C. Output voltage is in phase with an input signal
D. Output voltage is out of phase w.r.t. input by 180°

a. A & D
b. A & C
c. B & D
d. B & C

Correct Answer : b. A & C

Explanation :

Non-inverting amplifier has greater output voltage than that of its input voltage & is in phase with it. On the contrary, the output voltage of inverting Op-amp goes out of phase in correspondence to input signal by an angle of 180° or in terms of opposite polarity. In case of non-inverting amplifier, the input is applied to non-inverting input terminal & inverting terminal is set to be grounded while in case of inverting amplifier, the input is applied to inverting terminal & non-inverting terminal is at ground level. Therefore, due to the configurational assortments in inverting & non-inverting amplifier, the output voltage & phase level (in or out) also exhibit variations.
