2- Assuming that the diodes in the circuits below are ideal, utilize Thévenin theorem to simplify the circuits and thus find the values for the labeled currents and voltages.
3- (D) For the rectifier circuits shown below, let the input sin wave have 120-V rms value and assume the diode to be ideal. Select a suitable value of R so that the peak diode current doesn't exceed 50 mA. What is the greatest reverse voltage that will appear across the diode?
4- In the diode circuit shown below, R1 = 2kΩ, R2 = 1kΩ, V1 = 12V and V2 = 15V. Determine the diode currents I1 and I2. Assume that cut-in voltage for both diodes is VΥ = 0.7V.
5- The diode circuit shown in the figure below has R = 30kΩ and VDD = 10V. Determine the current io and voltage vo if
