  • Q1. What is an ideal diode?. Draw its input output characteristic curve
  • Ans. 

    An ideal diode is a theoretical diode that exhibits zero voltage drop when forward biased and infinite resistance when reverse biased.

    • An ideal diode acts as a perfect conductor when forward biased.

    • It allows current to flow in one direction with zero voltage drop.

    • When reverse biased, it acts as an open circuit with infinite resistance.

    • The input-output characteristic curve of an ideal diode is a vertical line at zero vol...

  • Q2. Write a program for computing the factorial of a number using recursion
  • Ans. 

    Program to compute factorial of a number using recursion

    • Define a function that takes a number as input

    • Check if the number is 0 or 1, return 1 if true

    • Else, call the function recursively with n-1 as input and multiply with n

    • Return the result

    • Example: factorial(5) = 5 * factorial(4) = 5 * 4 * factorial(3) = 5 * 4 * 3 * factorial(2) = 5 * 4 * 3 * 2 * factorial(1) = 5 * 4 * 3 * 2 * 1 = 120

  • Q6. Tell us something about zener diode
  • Ans. 

    A zener diode is a type of diode that allows current to flow in the reverse direction when a certain voltage is reached.

    • Zener diodes are commonly used as voltage regulators.

    • They have a sharp breakdown voltage, which makes them useful for stabilizing voltage in electronic circuits.

    • Zener diodes are often used in power supplies, voltage references, and surge protectors.

    • They are also used in noise reduction circuits and as...
