Final answer:
When there is a 10 dB loss in power, only about 10% of the original power remains.
Step-by-step explanation:
When dealing with a 10 dB loss, this is a measure commonly used in Physics to represent a power ratio. In these terms, a 10 dB loss means that the power has reduced to one-tenth of its original value. To determine the percentage of the original power that remains, we can use the formula for decibel calculation which relates to power ratios. A decibel (dB) is defined as 10 times the logarithm (base 10) of the power ratio. So reversing this process:
- 10 dB = 10 * log(power ratio)
- 10/10 = log(power ratio)
- 1 = log(power ratio)
- Power ratio = 10^1
- Power ratio = 10
This ratio implies that the original power has been divided by 10, which means 10% of the original power remains after a 10 dB loss. Considering that the percentage of original power is key, this calculation shows that approximately 10% of the original power is what we end with after experiencing a 10 dB loss.
