WebAs a final note, Kirchhoff's laws depend on certain conditions. The voltage law is a simplification of Faraday's law of induction, and is based on the assumption that there is no fluctuating magnetic field within the closed loop.Thus, although this law can be applied to circuits containing resistors and capacitors (as well as other circuit elements), it can only … WebMar 6, 2024 · Kirchhoff's second law obeys the law of conservation of energy. This can be understood from the sentences below. The amount of charge gained is equal to the amount of energy lost in a closed loop. The resistors in this closed circuit are to blame for the energy loss. Furthermore, the total voltage loss across the closed circuit should be zero.
