Quiz zum Vortrag
What is the difference between AC and DC circuits?
- AC circuits have a current which changes in direction and magnitude periodically.
- AC circuits have no resistance.
- AC circuits have an unknown voltage source.
- AC circuits are the realization of the DC circuits of theory.
- AC circuits have no voltage drops.
Why do we measure the RMS current or voltage instead of the average value over a period in AC circuits?
- Because the average value is 0
- There is no actual voltage or current in AC circuits.
- The average values are not easy to calculate.
- The current and voltage switch places with each other too rapidly.
- The average values have square roots of negatives, so are undefined.
Which of the following is true about the RMS current in an AC circuit with sinusoidal current?
- It is 1/√2 times the maximum current
- It is the square root of 2 times the maximum current
- It is half the maximum current
- It is twice the maximum current
- It is equal to the maximum current
