Kirchhoff's voltage law implies that the voltage across the resistor will rise at the same rate.

The voltage rises to its maximum value in the saturation stage, and thereafter it undergoes fluctuations of the various stages; while the current progressively increases throughout.

"Under certain conditions, which occur infrequently but are unavoidable, voltage can rise to 20, 30 or 50 percent over normal," which is 110 to 120 volts, he said.

As a lamp gets older, the maintaining voltage for the arc eventually rises to exceed the voltage provided by the electrical ballast.

If the voltage rises above 120 volts, there is a problem, and a surge protector helps to prevent that problem from destroying your computer.

These voltage variables must be defined as voltage rises with respect to the reference node.

The voltage across the electrodes then rises and the spark re-forms at the bottom of the device.

In some cases, several separate lamps are used with resistive voltage dividers arranged to allow additional lamps to strike as the applied voltage rises higher.

When the voltage rises above the normal range, the diodes become forward-biased (conducting).

In any case, if there are no components to absorb the current, the voltage at the switch rises very fast.
