For an operational amplifier, the output resistance is the resistance between
Correct answer: C. output terminal and ground
- A. inverting input and ground terminal
- B. non-inverting input and ground
- C. output terminal and ground
- D. Input and output terminal
Explanation
The output resistance of an operational amplifier is primarily determined by the resistance between the output terminal and ground. Operational amplifiers are designed to have low output impedance to provide a stable output voltage.Incorrect Options and Explanations: (a) inverting input and ground terminal - The inverting input is not directly related to the output resistance of the operational amplifier. (b) non-inverting input and ground - The non-inverting input is not directly related to the output resistance of the operational amplifier. (d) Input and output terminal - The output resistance is not determined by the resistance between the input and output terminals.

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.
