A negative voltage of several thousand volts is applied between wire and plate.

By increasing the negative voltage electron backstreaming can be avoided.

This results in a negative voltage across the inductor and drains it.

Consider first a surface biased to a large negative voltage.

This will be a negative voltage under ordinary conditions.

"Zero" is represented by another level (usually a negative voltage).

It allows current to flow backwards with small negative voltages.

A negative voltage of the same magnitude toggles it to its low-resistance state.

The injured tissue has a negative voltage compared to the central part of the body.

To record physical data, the zero-crossing from positive to negative voltage of the analog signal is measured.
