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?

The figure below shows a first-order active low pass filter.   You are given that C = 33nF and RB = 2kΩ. (a) For a cutoff frequency of 2000 Hz, what value of R should you choose? (Answer to the nearest ohm)

The following schematic is a linear power supply circuit. If the measured peak-to-peak voltage from node A is , calculate the Vrms of this node. Express your answer in volts (rms).
