When you connect the load at the receptacle, the hot-to-ground receptacle source voltage should be the sum of the hot-to-neutral voltage (the voltage across the load) and the neutral-to-ground voltage (the voltage drop on the neutral wire all the way back to its connection to the ground circuit) (Fig. 2 on page 34).
vestige (vesËÂ·tij), n an organ that has developed imperfectly and is largely considered nonfunctional. It may have provided a significant function in a more primordial type of life or during an earlier life stage. The vermiform appendix in humans is an example of a vestige.
Vestigial describes an organ or body part that continues to exist without retaining its original function, such as our appendix. The adjective vestigial derives from the Latin word vestigium, meaning footprint, trace.. It's most often used in biology to describe something that either didn't finish developing or has become, through evolution, pretty much useless. An ostrich's wings are vestigial because it's unable to fly â or do much of anything â with them. A penguin's wings, on the other hand, are not vestigial because it has found another use for them â to help it swim.
