Answer with clear writing please
5. Consider an idealized diode with a reverse saturation current 0.01 mA and an abrupt turn-on voltage of 0.7 V (assume no breakdown and operation away from the knee of the diode curve). For the circuit shown, both resistors are 100 Ω, the constant source is VP-7.0 V, and the time- dependent source is Vs 24 sin() V. Calculate (a) the peak positive voltage V and the associated current through the diode and (b) the...

Ctri Question 3 (20 Marks) Lab 1-Zener Circuits and Applications Theory: Zener diode is designed to operate in reverse conduction. Zener breakdown occurs at a precisely defined voltage, allowing the diode to be used as a voltage reference or clipper. While Zener diodes are usually operated in reverse conduction, they may also be operated in cutoff and forward conduction. There are two different effects that are used in "Zener diodes". The only practical difference is that the two types have...
