Exercice 52 : Loi d'Ohm aux bornes de trois dipôles Les caractéristiques tension-intensité des trois dipôles (conducteur ohmique,
ne générateur et récepteur), ont pour équations :
, I = U, et I = 3–6U
U = 6-

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
