What happens during regulation action of aZener diode?

1.	What happens during regulation action of aZener diode?
Answer» The current and voltage across the ZENER remains fixed. The current throughthe series Resistance `(R_(s))` changes. The Zener resistance is constant. The resistance OFFERED by the Zenerchanges. Solution :When zener diode is used as a voltage regulator, WHENEVER input voltage changes, current passing through zener diode and series resistance changes. Thus option (B) is correct. (n the present case, output voltage `V_(Z)` remains constant across zener diode. But after the breakdown, resistance of zener diode goes on decreasing gradually and so zener current `I_(Z)` goes on increasing rapidly. Thus, option (D) is also correct.

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
