These devices can also be biased so that they will switch between two states very quickly, as the applied voltage changes.

For large voltage changes, a transformer (isolated) topology may be better.

As the two resistance changes are equal and opposite, the effective voltage change is twice the individual change.

So with more current, voltage changes faster, which allows faster signalling over the bus.

These devices keep the current flowing through them unchanged when the voltage changes.

Like other researchers in that field, he measures voltage changes caused by the interaction of liquids with solids.

These voltage changes are amplified and used to record or transmit sounds.

Most current-clamp amplifiers provide little or no amplification of the voltage changes recorded from the cell.

To discharge the node, added electrons must be removed one at a time, which needs a definite voltage change.

Many are also time-dependent-in other words, they do not respond immediately to a voltage change, but only after a delay.
