Most part of the electric power-driven machinery are geared up to function using a particular frequency and current. The difficulty with this seemingly basic idea is that voltage and frequency differ by country and sometimes even by area inside a country.

The solution to the current and frequency crisis is transformers. What transformers perform is get the voltage and regulate it as it comes into the electrical device or appliances to the accurate level. They also push the current throughout the engine to keep it running properly.
