Question 475Electricity & Electronics - Assistant Engineer

The correct answer is B) ripple. Ripple is the correct term for the fluctuation of voltages shown in figure "H" of the illustration EL-0085. Ripple refers to the small, rapid variations in voltage that can occur in electrical systems, often due to incomplete filtering of alternating current (AC) signals. This is a common phenomenon in power supplies and other electrical circuits. The other answer choices are not accurate descriptions of the voltage fluctuation depicted in the illustration. Swell, wave, and roll are not the proper technical terms for this type of voltage variation.
