- C. electric, magnetic
- D. static, dynamic
Answer: A
Explanation:
Explanation
The two main applications for AC (alternate current) are power and information. AC is used to generate and transfer power to electrical devices, and is also used to carry information signals in telecommunications.
NEW QUESTION # 19
If a waveform period is determined to be 10 microseconds in duration, what is the frequency of the signal?
- A. 10 kHz
- B. 100 Hz
- C. 1000 Hz
- D. 100 kHz
Answer: D
Explanation:
Explanation
Frequency is the inverse of period, so to calculate the frequency of a signal with a period of 10 microseconds, you would divide 1 by the period, which is equal to 100 kHz.
