Please help me with these diode questions

What is the purpose of waiting 1 s after a voltage pulse before measuring current in sampled current voltammetry?

For the circuit shown in figure 1, the diodes is in complete model and the resistance of both diodes are 5 Ohm. Find the current in the resistance RL. When the both switch S1 and switch S2 are ON. v1= 6V, V3 =3 Vv2=12 V.

Can you draw me a half size breadboard circuit with a 9V source, a multimeter, 220ohm resistor in series and a 1N914 forward biased diode? Im reading about 9.8mA and others are reading 35.02mA. Can you tell me what about it should read for current and voltage? The simulation has two multimeters but we only use one for the live experiment. I feel like Im getting low current reading so I may have it wired wrong.

Determine the current flowing through resistor R2. (assume Zener voltage is 3 volts and Diode forward voltage is 0.7V)

What special type of diode is used in the circuit? Given the state of the switch as shown, what is the state of the diode? If the threshold voltage of the diode is 1.5V, what is the diode current?

Determine the current at the resistor R1. (assume LED forward voltage is 2.1 volts and Diode forward voltage is 0.7V)

Briefly explain how to came up with your answer to each number and please show your complete solution. I want to learn how to solve this problem. Thank you!!

If a Zener diode has 15 volts across and 20mA of current flowing through it, what is the Zener power dissipation? please answer it clearly.

Please explain the semiconductor diodes and give me questions with solutions and all formulas, I have exam .

I don't know what will be the figure of example 2. Please help. Thank you.

Moving to another question will save this response. Quèstion 2 The density of doping of zener diode is less than normal diode. True False Moving to another question will save this response.

A Zener diode has a Zener resistance of 5Ω. If the current changes from 10mA to 20mA, what is the voltage change across the Zener diode? Please answer it clearly.

Moving to another question will save this response. Question 23 During the analysis of diode circuits, the forward resistance will be considered if .model is used ideal complete perfect constant voltage drop > A Moving to another question will save this response.
