Us (actually, "backwards" u, with tail on the bottom lefthand side)

Explanation:
Resistance measurement. Plural of U (or, actually, a **backwards** "u"--that is, one with the tail on the bottom lefthand side, rather than the right. This symbol, however, requires an expanded set of ASCII/ANSI, something not available on this ProZ site, nor in many wordprocessing systems. Hence, the U.

"U : différence de potentiel entre les bornes de la résistance.
Autrement dit, Dans un circuit électrique, le passage du courant électrique dans une résistance provoque une chute de tension
égale à la différence de potentiel entre ses bornes."

Here are some examples:

Le Diviseur de tension divise la tension électrique fournie par le générateur et permet donc d'avoir, selon les valeurs des
résistances R1 et R2, toute une plage de valeurs de la tension électrique.
Cherchons l'expression de la tension de sortie Us en fonction de E, R1 et R2
La loi d'Ohm nous apprend que :
Us = R2 x I.
D'une autre part la loi d'additivité des tensions nous permet d'écrire :
E = (R2 + R1) x I.
Nous en déduisons la loi de variation de la tension Us à la sortie du diviseur de tension :
Us = R2 x E / (R2+R1.
Nous remarquons que la tension de sortie us peut prendre toutes les valeurs possibles comprises entre 0 et E.

Here is an example in English:

to satisfy this equation one could use twelve 1000 uF capacitors if the ESR of each was 53 m . The parallel resistance of 12 capacitors would be 4.4 m and the parallel capacitance would be 12,000 uF, which falls in the white zone of the graph in Figure 16.

 Thanks!

disagree  Tony M: Even though it COULD be 'sortie', it is quite clear from Asker's context that it is specifically referring to the supply or input voltage

tension Us

Explanation:
Clearly, from the context, must be 'supply OR mains voltage'

U is a commonly used and preferred abbreviation in Europe for V = voltage

The reply involving the 'backwards u with a tail' is dangerously innaccurate -- for a start, this is the Greek letter mu, and is the SI abbreviation for micro- i.e. millionth as a mutliplier -- so uF is microfarad
So it has nothing to do with a unit, and certainly not of resistance!

The mu symbol referred to above looks like this: µ

\'Supply voltage\' or Vs in English --- note that the tolerance is expressed as being Vsupply +/-10%
