A diode’s resistance in forward bias is measured using a digital multi-meter. Which answer approximately shows a correct resistance value showed by the multi-meter?

Assume Vin = 2V, Vdiode_on = 0.7V, R = 1kΩ.  With RL = 10kΩ, what is the current that flows into output load RL? Provide your answer in mA.

For the circuit as shown below, Vin= 20 V, R1=15 Ω, R2=R3=10 Ω. What is the value of Vout in volts?

In the following frequency response plot blow, find the cutoff frequency.

A Zener diode is specially designed to operate in the ________________ region

For the given oscilloscope screen, calculate the period of the signal (in second). Note: volt/div = 2 Volts/div            time/div = 1 ms/div

In the bridge rectifier bellow at first we increase C1’s value then we increase R1 value. Choose the correct answer.

Which of the following statements are correct: A. The electrical power that we get from the wall outlets is 120V AC(volts, alternating current).  B. The bridge rectifier is the first step in AC to DC conversion. C. A bridge rectifier is an arrangement of four diodes to convert a bipolar AC waveform into a unipolar waveform. D. One way to help regulate the output (AC to DC conversion) is to add a filter capacitor to the output. The larger the capacitor, the more energy it can store, further reducing the ripple effect.

What is the general function of this circuit?

An ac power module connected to a power outlet in Bangladesh is supplying to a Bridge rectifier circuit (lab 8 setup). The output of the rectifier has a frequency of 100Hz. What is the power line frequency (in Hz) in Bangladesh?
