A negligible small current between input terminals of the operational amplifier is because of:
Correct answer: C. High input resistance
- A. High output resistance
- B. Low output resistance
- C. High input resistance
- D. Low input resistance
Explanation
Ideal op-amps have zero input current. A small input current passes because of very high input impedence.

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.
