Which result is produced using a power ratio of 10:1 in standard decibel calculations?

• A.-20 dB
• B.5 dB
• C.10 dB
• D.15 dB

Correct Answer: C

In decibel calculations, the formula used to convert a power ratio to decibels (dB) is:
Thus, the power ratio of 10:1 corresponds to a 10 dB change in power.
Option A: -20 dB would correspond to a ratio of 0.01:1, not 10:1.
Option B: 5 dB would correspond to a power ratio of approximately 3.16:1, not 10:1.
Option D: 15 dB would correspond to a ratio of 31.62:1, not 10:1.
Therefore, Option C: 10 dB is the correct answer, as it is the result of a power ratio of 10:1.
