As voltage decreases, so does the current, releasing spring tension or the weight of the core and causing it to retract.

You should know that every time someone else picks up the phone line, then the voltage does decrease a little.

If the storage cell is charged, the bit-line's voltage only decreases very slightly.

This makes the provided reactive power decrease rapidly when voltage decreases, thus reducing its stability.

The voltage necessary to arc across the gap decreased as the pressure was reduced and then increased gradually, exceeding its original value.

When the voltage decreases, it slips back.

This energy would otherwise remain untapped because many applications do not allow enough current to flow through a load when voltage decreases.

The voltage across an arc decreases as the current increases, giving it a dynamic negative resistance characteristic.

The voltage of alkaline cells decreases steadily during most of the discharge cycle.

High voltages also decrease the resolution (above about 5 to 8 V/cm).
