The electricity generated is transformed into the higher voltages – up to 400,000 volts – used for economic, efficient transmission via power line grids. When it nears the point of consumption, such as our homes, the electricity is transformed down to the safer 100-250 voltage systems used in the domestic market.
How does voltage affect power consumption?
The higher the voltage the higher the power consumption in the case of a pure resistance load. A reduction in voltage does not affect the energy used by the domestic appliances which use resistive loads except in devices such as kettles and toasters which will take longer to do their job due to atmospheric losses.
