Which of the following describes alternating current electricity?
- a. It can be produced by rotating a loop of wire through a magnetic field.
- b. It flows in one direction for a period of time and then reverses direction.
- c. It goes through one cycle when it flows in one direction and then reverses direction.
- d. All of the above.
Find the right option.
Answer to Problem 1RQ
The right option is “d. all of the above”.
Explanation of Solution
Refer to Figure 19.1 in the textbook for alternating current electricity. An alternating current is produced by rotating the loop of wire through a magnetic field alternates in direction. In alternating current electricity, electron flows in the conductor first in one direction for a period of time then changes the direction and flows in opposite direction (that is, reverse direction). Thus, current is alternating to and for almost relatively fixed positions.
Conclusion:
Hence, the correct option is “d. all of the above”.
