Diodes are essentially one-way valves. They carry current in one direction, but block current in the other. In addition, in the forward conduction mode, the voltage must go above a threshold before significant conduction occurs. A 12.0V stabilized power supply is required to be produced from a 24V DC power supply input source. The maximum power rating Pz of the Zener diode is 4W

R.
With the loop equation, Vs = Vd + Vr = Vd + I*R
Using the Zener regulator circuit calculate:
a) The maximum DC current flowing through the Zener diode
b) The minimum value of the resistor.
c) If the whole process took 15seconds to complete what would be the energy released in
the circuit?
d) What would happen if the supply voltage is turned off in the circuit?
