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?

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)

Q*: Calculate the current through 48 Q resistor in the circuit shown in Figure(i).Assume the diodes to be of silicon and forward resistance of each diode is 1 Q. D D2 48 2 ww 10 V= D4 D3 (i)

Please help me with this worksheet. Please fill in the table, answer the questions and make both circuits A and B on Tink

Draw vx and v0 according to the input voltages in the circuit shown in the figure. note = R1 = 10Kohm R2 = 1kohm R3 = 1Kohm, the threshold voltages of diodes will be VE = 0.7V.

A PMMC type meter has a full scale deflection of 10 mA. The resistance of the coil is 30 ohm. Then (1) shunt value for an Ameter of 50 A range and (2) Find the value of series resistance required for the range up to 500 V.

Hi, can you help me with this whole question please. Thank you
