Options

  1. AThe circumcentre of a triangle lies at the origin and its centroid is the midpoint of the line segment joining the
  2. BThe circumcentre of a triangle lies at the origin and its centroid is the midpoint of the line segment joining the
  3. CThe circumcentre of a triangle lies at the origin and its centroid is the midpoint of the line segment joining the
  4. DThe circumcentre of a triangle lies at the origin and its centroid is the midpoint of the line segment joining the

Correct answer

C. The circumcentre of a triangle lies at the origin and its centroid is the midpoint of the line segment joining the

Step-by-step solution

At time t=0,t = 0, voltage across the first zener diode is increases linearly till it reaches it's breakdown voltage of 4V4V, after that voltage increases linearly till it reaches the breakdown voltage of second zener diode,

As soon as voltage across the zener diode reaches the breakdown voltage of 6V6V of second zener diode, volatge becomes constant and doesn't change with time.
