What is the function of a converter in electrical systems?

It increases current flow
It changes AC to DC
It changes DC to AC
It stores electrical energy

The correct answer is: It changes DC to AC

The function of a converter in electrical systems is to change DC (direct current) to AC (alternating current). This conversion process is essential in various applications where the power supply needs to be compatible with the devices being used, such as in residential or commercial electrical systems that primarily operate on AC. Converters play a critical role in ensuring that electrical devices receive the correct type of current they require for optimal operation. For instance, in solar panel systems, the DC generated by the panels needs to be converted to AC for use in homes or for feeding into the electrical grid. While there are devices that serve to increase current flow, such as amplifiers, or those that store electrical energy, like batteries, those functions are not the primary purpose of a converter. The main focus of a converter lies specifically in transforming the type of current, highlighting its importance in modern electrical systems.
