Why is the supplied voltage in the powerline wires an integral multiple of 11 from the supplier? Example -- That line is 11,000V

A transformer is an electrical device that is used to increase or decrease the voltage of an alternating current (AC) electrical supply.
A transformer works by passing an alternating current through a primary coil, which creates a magnetic field. This magnetic field then induces a current in a secondary coil, resulting in a change in voltage.
The purpose of applying voltage with a transformer is to change the voltage level of an electrical supply to suit the needs of different devices or systems. For example, high voltage is required for power transmission, but lower voltage is needed for household electronics.
No, a transformer can only increase or decrease voltage within a certain range, known as the transformer's turns ratio. Going beyond this range can cause damage to the transformer and the devices connected to it.
The voltage output of a transformer is determined by the number of turns in the primary and secondary coils and the type of core material used. The turns ratio, which is the ratio of the number of turns in the primary coil to the number of turns in the secondary coil, also plays a crucial role in determining the voltage output.
