Explanation:
It is given that,
The signal to a speaker causes 0.5 amps of current,
The signal level is increased to 2.5 amps,
We need to find the gain to the nearest decibel. The decibel gain formula of the speaker is given by :
db = 13.97 db
or
db = 14 db
So, the gain pf the speaker is 14 db. Hence, this is the required solution.
