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 Ω and 200Ω . 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
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
