Second law of commutation

Lecture



The voltage across the capacitor cannot change abruptly, i.e. U (0-) = U (0+)
Consider the RC circuit

Second law of commutation

The equation according to the second Kirchhoff law:

E = iR + Uc

t (0-) → Uc (0-) = 0

t → ∞ Uc = E

Evidence:
Suppose that Uc changed abruptly, then Second law of commutation therefore, an infinitely large electrical power cannot be.
