A drop in voltage can be more serious than a power cut.

It is equal to the difference in voltage between the object and a point some distance away.

The brownouts, he said, were brought about by an 8 percent reduction in voltage into some of the areas.

As we'll see later on, various factors can cause a brief increase in voltage.

What will kill you is the difference in voltage between the car and the ground.

This increase in voltage constitutes the rising phase of an action potential.

This drop in voltage tells the printer that data is being sent.

The resulting change in voltage can be utilized for the measurement.

The change in voltage is detected and made visible on a control panel.

Changes in voltage can then be plotted over a period of time.
