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...read more

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

A lance is a long, pointed weapon used in medieval warfare.

• Lances were typically made of wood or metal.

• They were used by knights on horseback to charge at their enemies.

• The length of a lance varied, but it was usually between 9 and 14 feet long.

• Lances were often decorated with banners or flags to identify the knight carrying it.

• The use of lances declined with the advent of firearms in warfare.

Tilt drive is a mechanism used in construction to tilt heavy objects or structures.
