The value of power dissipated across the Zener diode ( Vz = 15V) connected in the circuit as shown in the figure is x x10-1 watt. The value of x, to the nearest integer, is--------.
If the multimeter shows zero or low resistance reading for forward bias and does not change even on reversing the connection then the diode is defective. It is short.
If the diode shows a high resistance under both forward and reverse biased conditions, it is defective. It is open.
