Question

A full wave rectifier is operating at \(50 \mathrm{~Hz}, 220 \mathrm{~V}\) the fundamental frequency of ripple will be (A) \(50 \mathrm{~Hz}\) (B) \(75 \mathrm{~Hz}\) (C) \(110 \mathrm{~Hz}\) (D) \(100 \mathrm{~Hz}\)

Short answer

The frequency of the ripple produced by a full-wave rectifier is found using the formula Ripple frequency = 2 * Input signal frequency. In this case, the input signal frequency is 50 Hz, so the ripple frequency is 2 * 50 Hz = 100 Hz. Therefore, the correct option is (D) \(100 \mathrm{~Hz}\).

Step-by-step solution

Full-wave rectifier ripple frequency formula

To find the ripple frequency of a full-wave rectifier, we use the following formula: Ripple frequency = 2 * Input signal frequency

Input signal frequency

In this problem, the input signal frequency is given as 50 Hz.

Calculate the ripple frequency

Now, we can apply the formula to calculate the ripple frequency: Ripple frequency = 2 * 50 Hz = 100 Hz

Choose the correct option

Based on our calculation, the ripple frequency of a full-wave rectifier operating at 50 Hz is 100 Hz. Hence, the correct option is: (D) \(100 \mathrm{~Hz}\)
