ASVAB Practice Test

What does the abbreviation AC stand for?

1. Alternating Current

2. Air Conditioning

3. Amplified Circuit

4. Active Current

The correct answer is: Alternating Current

AC stands for Alternating Current, which refers to a type of electrical current that periodically reverses direction. This is the most common type of electricity used in homes and buildings. Option B, Air Conditioning, is incorrect because it refers to a system that cools and circulates air, and has nothing to do with electrical current. Option C, Amplified Circuit, is incorrect because it does not accurately describe AC and the term "amplified" is often associated with audio equipment. Option D, Active Current, is incorrect because it is not a commonly used term and may be confused with other types of current such as direct current (DC). Therefore, option A is the best answer as it accurately reflects the meaning of the abbreviation AC.
