Voltage is not "used" Voltage is constant.
a voltmeter is used to measure voltage
If the voltage needs to be increased from a lower voltage to a higher voltage a step up transformer is used. If the voltage needs to be lowered from a higher voltage to a lower voltage a step down transformer is used.

The voltage used in Ireland is 220V AC, at 50Hz.
Voltage dividers are used in a linear circuit to separate the input voltage into a small portion known as the output voltage. It is commonly used to get a low voltage signal equal to the voltage being measured.
5 voltage dc
230 voltage is used by the microprocessor
The standard voltage used in Brazil is 127 volts.
To convert the high voltage on a feeder line to a lower voltage that can be used on the plant floor you use a transformer.
Line to Ground voltage = line to line voltage / 1.73AnswerIt depends what configuration is being measured. In the case of the secondary of a split-phase distribution transformer used to supply residences in North America, the answer is yes. In the case of a star (wye) connected secondary distribution transformer used to supply residences in Europe, no: the line to ground voltage will be as described in the first answer.
