A zener-regulated power supply consists of a 9 V battery connected in series with a resistance of 100 Omega and a zener diode. The zener diode maintains a constant voltage drop of 4 V across a load resistance of 400 Omega . The current drawn by the load resistance will be

Zener diode is a specially desined p-n junction diode, in which both p-side and n-side of p-n junction are heavily doped. The zener diode is designed especially to operate in the reverse break down voltage region continuosly without being damaged? Zener diode is used to remove the fluctuations from the given voltage and thereby provides a voltage of constant magnitude (i.e., Zener diode is used as voltage regulator). Read the above pragraph and answer the following question: (i) What is the most important use of Zener diode? (ii) What are the essential conditions for proper working of Zener diode? (iii) What do you learn from the above atudy?

In a zener-regulated power supply a zener diode with V_(Z)=6 volt is used for regulation. The load current is to be 4mA and the unregulated input is 10 volt. What should be the value of series resistor R_(S) , if the current through diode is five times the load current ?
