condensateur suite 4

Objectif : 
calculer la capacité d'un condensateur 


1. On peut calculer la capacité d'un condensateur à partir de la formule C= Q/U. Vérifier dans le document photo la valeur de la capacité du condensateur. (Montrer votre calcul dans "comments" en bas de cette page 


 2. On peut calculer la capacité d'un condensateur d'après
 C=epsilon S/e
 avec epsilon est la permittivité du diélectrique

Dans la capsule vidéo on a demandé de vérifier 2 fois la valeur de C. Ecrire votre calcul dans "comments" en bas de la page

               =0.30×10×10^(-13)
               =0,30×10^(-12)F
               =0,30pF
    2) 1°fois:C=epison×S/=(100×10^(-6))÷(36pi×10^(9)×2×10^(-3))
    =4,4×10^(-13)F
    =0,44×10^(-12)
    =0,44pF
     
      2° C=epison×S/e

    1) C= Q/U = 0.21 x 10**(-12) / 0.700 = 3x 10**(-13) F => 3x10**(-13)/ 10**(-12) = 0,3 = 0.30pF.

    2) C=ℇoS/e :
    2.1) C = 1 x 100x10**(-6) / (36⫪ x 10**9)(2x10**(-3)) = 4,4 x10**(-13) F => 4.4 x 10**(-13) / 10**(-12) = 0.44 pF

    2.2) C' = 1x250**(-6) / (36⫪x10**9)(2x10**(-3)) ≈ 1.11x10**(-12)F = 1.11 pF.

    1)C=Q/U
    C=0,21x10*(-12)/0,700
    =3x10*(-13)F
    =0.30pF
    2)C=epsilonxS/E
    =(1/36pix10*(9))x(100x10*(-6))/2x10*-3
    =4,4x10*-13F
    =0,44pF:verifie
    C=epsilinxS/e

    1-)C=Q/U
    =(0.21×10^-12)/0.7
    =3×10^-13
    =0.3×10^-12 F
    =0.3 pF (vérifié)
    2-)•C= epsilon s/e
    = (100×10^-6)/(36pi×10^9×2×10^-3)
    = 4.4×10^-13
    = 0.44×10^-12 F
    = 0.44 pF (vérifié)
    •C= epsilon s/e
    = (250×10^-6)/(36pi×10^9×2×10^-3)
    = 1.1×10^-12 F
    = 1.1 pF (vérifié)
