Thank you sir, your videos are very helpful. Iz=2.67mA,VL=10V, current across 1k ohm is 6mA,Pz=26.7mW

Sir condition for zener diode to act as voltage regulator is v(input) greater than v(rever bias of zener ) or mod of v(input) greater than v reverse?

Ramji Shivhare The condition for Zenor doide to be act as an voltage regulator is that the applied voltage across the zenor diode must be greater than the rated zenor voltage so that we can get the constant output vz at load resistance. Hope u understand

@AdityaRaj-gj4dl Жыл бұрын

@@thecalm_soul If we consider load is equal to 3K ohm then calculate Vth. Vth is 12V. Since 12 > 10 zener diode in breakdown region.Since Zener is a voltage regulator voltage across load will remain 10 volts only.Use Nodal analysis. IR =(16-10)/1000= 6mA. Since Voltage across load is 10 volts, IL =10/3k =3.33m. Apply KCL in order get current through zener diode Iz=(6-3.33)mA=2.67mA. Pz =(Iz*Vz)=2.67*10=26.67mW.

Sir What's the difference between Vth and Vz? And zener conducts in reverse bias condition but why the diode is open circuited? In the problem.

@vamsikrishna9825 6 жыл бұрын

Kota Sriveni The difference between the vz and vth in above lecture is vz is the maximum output voltage that Zenor diode can give, but in order to give zenor output voltage constant the applied input voltage to the zenor must be greater than the vz. Then only the zenor diode will turn on . So to find input zenor voltage we find vth.
