A student gives input to a NAND gate as shown in the given diagram.
Correct answer: B. B
- A. A
- B. B
- C. C
- D. D
Explanation
The NAND gate produces an output of 0 only when all its inputs are 1. Otherwise, it outputs 1. In this question, the correct interpretation of the inputs given to the NAND gate results in option B being correct. The other options fail to correctly apply the NAND operation, either by mistaking it for an AND gate or by not considering the inversion of the logical AND operation.

About Rectification
Rectification converts alternating current into unidirectional current using semiconductor diodes. The content includes half wave and full wave rectifiers, bridge circuits, output waveforms, ripple and smoothing with capacitors, with the difference between rectification and voltage regulation kept clear.
