The Ferranti Effect will be more pronounced the longer the line and the higher the voltage applied.
A dimmer is a device used to vary the average voltage applied to an instrument's lamp.
A voltage applied to the grid controls the current flowing from the filament to the plate.
As the voltage applied to the varicaps is changed, the phase shift of the output will change.
By controlling the voltage applied across the liquid crystal, the amount of remaining twist can be selected.
Lowering the voltage applied at a higher temperature maintains safety margins.
A voltage applied to the gate can switch the current on and off within the silicon - the basis of digital electronics.
So, given a constant potential (voltage) applied across the wire, the current would be smaller at higher temperature.
Electrical soft starters can use solid state devices to control the current flow and therefore the voltage applied to the motor.
With the voltages applied, the current flow through the sheet will emulate the field distribution.
