Question:
Which one of the following statements is correct?
Which one of the following statements is correct?
Show Hint
Remember that AC periodically reverses direction and its magnitude can vary, while DC flows in a constant direction with a constant magnitude.
Updated On: Apr 17, 2025
- AC changes its magnitude but not direction
- DC changes its magnitude and direction
- DC changes its direction only
- AC changes both its magnitude and direction
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Alternating current (AC) changes both its magnitude and direction periodically. In contrast, direct current (DC) maintains a constant magnitude but its direction can change depending on the external factors, such as polarity reversal.
