Final answer:
A 10db loss results in around 90% of the original power remaining, due to the logarithmic nature of the decibel scale.
Step-by-step explanation:
When there is a 10db loss, approximately 10 percent of the original power is lost, meaning that about 90% of the original power remains. This is based on the decibel scale which is logarithmic, and a 10 dB loss corresponds to a ten-fold decrease in power, equating to a 90% retention of the original power. It is important for students to understand that the decibel scale is used in various applications, including sound and electrical power, to describe ratios of power and intensity.
