When an Operational amplifier is used as Inverting amplifier, then angle between its output and input signal is:
Correct answer: E. 180 degrees
- A. 30 degrees
- B. 45 degrees
- C. 60 degrees
- D. 90 degrees
- E. 180 degrees
Explanation
In an inverting amplifier configuration, the input signal is applied to the negative input terminal of the operational amplifier. The output undergoes a phase inversion relative to the input, creating a 180-degree phase difference. This means that the output is the negative of the input at any given time, representing a complete inversion of polarity. Therefore, the angle between the input and output signals is 180 degrees.The other options are incorrect as they do not represent the characteristic phase inversion that occurs in an inverting amplifier. The angles of 30, 45, 60, and 90 degrees do not apply in this context because the inverting amplifier specifically results in a 180-degree phase shift.

About AC Through Resistor, Capacitor and Inductor
Alternating current through a resistor, capacitor and inductor involves phase relationships between voltage and current, reactance, impedance and energy transfer. A resistor keeps voltage and current in phase, while a capacitor and inductor produce opposite phase shifts, a distinction used in circuit diagrams and numerical calculations.
