Q2. What is peak factor
Ans. 
Peak factor is the ratio of peak value to the RMS value of a waveform.
• Peak factor is used to quantify the peakiness of a waveform.

• It is calculated by dividing the peak value of the waveform by its RMS value.

• A higher peak factor indicates a more peaky waveform with larger peaks relative to the average value.

• Peak factor is important in signal processing and power systems analysis.
