In a bridge full wave rectifier, the input sine wave is 250sin100πt.The output ripple frequency will be:

Correct answer: B. 100Hz

  • A. 50Hz
  • B. 100Hz
  • C. 200Hz
  • D. 25Hz

Explanation

The input signal is given as 250sin100πt. The angular frequency (ω) here is 100π, which corresponds to a frequency (f) of 50Hz (since ω = 2πf). In a bridge full wave rectifier, the output ripple frequency is twice the input frequency. Thus, 2 x 50Hz = 100Hz. Therefore, the correct answer is 100Hz. Options 50Hz and 25Hz are incorrect as they do not reflect the doubling of frequency in full wave rectification. 200Hz is incorrect because it overestimates the ripple frequency.

About Electronics

A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
