Kirchhoff’s Voltage Law (KVL) states that the sum of voltage drops in any closed circuit loop is zero, based on the principle of energy conservation.
Kirchhoff’s Current Law (KCL) states that the total current entering a node is equal to the total current leaving the node, based on the conservation of electric charge.
KVL can be used to calculate voltages in circuits and determine unknown voltage values, while KCL is useful for calculating current distribution in parallel circuits.
KVL and KCL are foundational tools for understanding and analyzing electrical circuits, applied in engineering, circuit simulations, power systems, and electronic devices.
