==Key Stage 5==
===Meaning===
[[Kirchoff's 2nd Law]] states that the sum of the [[Electromotive Force|electromotive force]]s (emfs) in any closed loop is equal to the sum of [[Potential Difference|potential differences (pds)]] in that loop.
===About Kirchhoff's Second Law===
*Also known as the '''[[Potential Difference|voltage]]''' law or '''loop rule'''.
*[[Kirchoff's 2nd Law]] is based on the [[Conservation of Energy|conservation of energy]].
*[[Kirchoff's 2nd Law]] is useful for solving complex circuits with multiple loops.
*The algebraic [[sum]] of the [[Product (Maths)|products]] of the Electrical Current|currents]] and the [[resistance]]s in any closed loop equals the [[sum]] of the [[Electromotive Force|emfs]] in that loop.
*[[Kirchoff's 2nd Law]] helps in setting up equations to solve for unknown [[Potential Difference|voltage]]s and [[Electrical Current|currents]] in circuit analysis.
*[[Kirchoff's 2nd Law]] is applicable to both [[Direct Current|DC]] and [[Alternating Current|AC]] circuits.
Used in combination with [[Kirchoff's 1st Law|Kirchhoff's first law]] for comprehensive circuit analysis.
===Examples===
*In a series circuit, the sum of the [[Potential Difference|voltage]]s across each component equals the total [[Potential Difference|voltage]] supplied by the battery.
*Applied to find the potential differences and emfs in electrical circuits.
