An amplifier has a power gain of 27,000. Express this in Bels (B) and decibels (dB).

The blue check mark means that this solution has been answered and checked by an expert. This guarantees that the final answer is accurate.
Learn more on how we answer questions.

In Bels, power gain =  log_{10} (27,000) = 4.431 B
In decibels, power gain

= 10 x log_{10} (27,000) = 10 × 4.431 = 44.31 dB
