Capacitor

\( C = \frac{Q}{U} \) \( C = \frac{\epsilon_r S}{4 \pi k d} \)

\( E = \frac{U}{d} \)

Procedure: \( E \propto \frac{Q}{S} \)

Proof: \( E = \frac{U}{d} = \frac{Q}{C \cdot d} = \frac{Q}{\frac{\epsilon S}{4 \pi k d} d} = \frac{4 \pi k Q}{\epsilon S} \)

Alternating Current

Procedure: Equivalent current

  • sine, cosine: \( I = \frac{I_{max}}{\sqrt{2}} \)
  • Calculate the average of \( I^2 \)

Procedure: Dynamic analysis of the circuit with internal resistance

Components connected in series: Inverted ratio Paralleled: proportional ...
