Key Concepts

Kirchhoff's Voltage Law

This law is an application of the conservation of energy in electrical circuits. It states that the algebraic sum of all electrical potential differences (voltages) around any closed loop in a circuit must equal zero, ensuring that the total energy gained and lost within the loop balances out.

Conservation of Energy

This fundamental principle in physics states that energy can neither be created nor destroyed but only transferred from one form to another. In the context of electrical circuits, it implies that the total energy supplied to the circuit is completely expended by the various circuit elements, ensuring that energy is conserved as it flows through the system.
