The amplification of the given operational amplifier is
Correct answer: B. inverting and double
- A. inverting and triple
- B. inverting and double
- C. non-inverting and triple
- D. non-inverting and double
Explanation
In an inverting configuration, the input signal is applied to the inverting input terminal (-) of the operational amplifier. The output signal is then inverted and amplified based on the ratio of the feedback resistor to the input resistor. This configuration results in a negative gain. The term "double" indicates that the amplification factor is 2. This means that the output signal is twice the magnitude of the input signal, but with opposite polarity. This is the correct option. It correctly identifies the operational amplifier as being configured in the inverting mode and having an amplification factor of two.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
