June 05, 2022 Posted by AK 2 comments

 An AC voltage of 24 V is connected in series with a silicon diode and load resistance is 500 ohm having forward resistance 10 ohm. Calculate the peak output voltage.


IF YOU ARE NOTICING ANY ERROR KINDLY CCOMMENT BELOW




SOLUTION

As the diode is connected in series the effective resistance 

R = RL + Rf

    = 500 + 10

    = 510 ohm


V = 24 V

Peak current = V / R

                     = 24 / 510

                     = 0.047 A


Peak output Voltage = Peak current x RL

                                 = 0.047 x 500

                                 = 23.5 V

  1. this voltage is given ac and always ac voltage is rms value and we have to calculate the peak value.

  2. one more thing i like to add that silicon diode is mentioned in the question so we have to consider 0.7 v, correct me if i am wrong...
