A logic gate has four inputs. Its possible input combinations will be:
Correct answer: B. 16
- A. 4
- B. 16
- C. 32
- D. 64
Explanation
This can be calculated using the formula 2n, where n is the number of possible inputs. The number of inputs is 4. Each input will take 0 OR 1 as values Therefore 24 = 16 possible combinations of inputs are there as

About PN Junction
A PN junction forms when p type and n type semiconductor regions meet, creating a depletion layer and a potential barrier. The topic covers forward and reverse bias, diode current voltage characteristics, breakdown and rectification, while distinguishing an ordinary junction diode from a transistor formed from multiple junctions.
