# Answer to Question #55074 in Electric Circuits for ARUN

Question #55074

a) With the help of a circuit diagram explain, how regenerative feedback is provided in

Hartley oscillator.

b) Design and draw a zener voltage regulator to provide 10V output if load resistance varies

between 50 and 200. Assume that the input unregulated dc voltage is 15V and

minimum zener operating current is 10 mA. Calculate the wattage of the Zener diode,

value and wattage of RS

.
