Please help me with these diode questions

In the figure below, calculate the following (use the second diode approximation): Np: N₂ 6:1 Vp 120 Vac 60 Hz (a) Vs (b) Vout(pk) (c) Vdc rü D₁ D₂ Vout R₁-2000) (d) IL (e) PIV of the diodes (f) fout

Explain how you could use an ohmmeter to identify the cathode of an unmarked diode. Why is it necessary to know the actual polarity of the ohmmeter leads?   *in your own words

Solve question no.3 and show a clear and organized solution. Write the GIVEN and REQUIRED. Thanks!!!

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)

Find R. (See figure 1 and 2)

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)

In this Zener diode regulator, the source voltage varies from 6 V to 11 V. Assume that the load current varies between 2 mA and 48 mA, and that the diode is an ideal 4 V Zener diode. What is the largest allowable resistance that will ensure the load voltage remains constant with variations in load current and source voltage? Please enter your answer to 3 significant figures.     Please answer in typing format solution please only typing format solution please

hi all. can you solve the problem below as quickly? thank you...

electronic device  Diode

For the circuit in the figure, let V input = 8V, Ri = 12ohms, RL = 10ohms, and VZ = 3.3V. Determine the voltages and currents of the resistors and the current of the zener diode.
