A more thorough explanation:

A qualified voter is someone who meets the requirements to vote in an election. This person is also known as a qualified elector.

For example, in the United States, a qualified voter must be a citizen of the country, at least 18 years old, and registered to vote in their state. They must also not have any felony convictions that would prevent them from voting.

Another example is in India, where a qualified voter must be a citizen of the country, at least 18 years old, and registered to vote in their constituency. They must also not be declared mentally unsound by a court of law.

These examples illustrate that a qualified voter must meet certain criteria in order to participate in the democratic process of voting. It is important for individuals to understand and meet these requirements in order to exercise their right to vote.
