Kondensator

Question 1

Feldstärke E

Accepted Answer

$E = \frac{U}{l}$ ------------------------ $[E] = \frac{V}{m}$ $[E] = \frac{kV}{mm}$

Question 2

Kapazität C

Accepted Answer

$C = \frac{Q}{U}$ ------------------------ $[C] = \frac{As}{V} = F$

Question 3

Flussdichte D

Accepted Answer

$D = \frac{Q}{A}$ ------------------------ $[D] = \frac{As}{mm^2}$

Question 4

Materialgröße ε (epsilon)

Accepted Answer

$ε = ε_0 × ε_r$ ------------------------ $[ε_0] = 8,85 × 10^{-12} \frac{As}{Vm}$ $[ε_r] = relativer Materialwert (ε_rLuft = 1)$

Question 5

Kondensator: mit 2 Platten

Accepted Answer

$C = \frac{ε × A}{l}$

Question 6

Kondensator: mit mehreren Platten

Accepted Answer

$C = (n - 1) × \frac{ε × A}{l}$

Question 7

Kondensator: Kugel mit Luft

Accepted Answer

$C = 4π × r × ε_0$

Question 8

Kondensator: Wickelkondensator

Accepted Answer

$C = \frac{2 × ε × A}{l}$

Question 9

Kondensator Reihenschaltung

Accepted Answer

$U_{ges} = U_1 + U_2 + U_3$ $Q_{ges} = konstant$ $C_{ges} = \frac{1}{\frac{1}{C_1} + \frac{1}{C_2} + \frac{1}{C_3}}$

Question 10

Kondensator Parallelschaltung

Accepted Answer

$U_{ges} = konstant$ $Q_{ges} = Q_1 + Q_2 + Q_3$ $C_{ges} = C_1 + C_2 + C_3$
