The Answer of When the volume control on a stereo system is increased, the voltage across a loudspeaker changes from V₁ to V₂, and the decibel increase is given by $d b = 20 \log \frac { V _ { 2 } } { V _ { 1 } }$ Find the decibel increase if the voltage changes from 1.7 volts to 3 volts. A) db = 4.9 B) db = 8.7 C) db = 7.2 D) db = 11.4 E) db = 3.8

When the Volume Control on a Stereo System Is Increased db=20log⁡V2V1d b = 20 \log \frac { V _ { 2 } } { V _ { 1 } }db=20logV1​V2​​

When the Volume Control on a Stereo System Is Increased $d b = 20 \log \frac { V _ { 2 } } { V _ { 1 } }$
