I'm having problem with the usage of articles for the word "power", namely "launch power" (the power at the input of a glass fiber):
"power" is uncountable in this case:
Power" can also mean physical force or energy, like electricity. This meaning is uncountable.see English Club
Now I wish to use it in sentences in my thesis, for instance:
Table 5.5 shows the magnitude of the first five coefficients given a launch power of −10, 0, and +10 dBm in the case of transmission over 100 km.
If power is uncountable, I should not be using the article "a". However, using no article makes the sentence sound strange and probably also wrong:
Table 5.5 shows the magnitude of the first five coefficients given launch power of −10, 0, and +10 dBm in the case of transmission over 100 km.
Would the definite article "the" be the proper solution here (even though I think it is not the right determiner in this case...)?
I have searched in the internet and found some sources regarding countable and uncountable nouns. Non of them seem to tackle my problem. I hope someone has a good answer for this problem, and maybe also a general rule about similar cases.
