Key Stage 5
Meaning
Kirchoff's 2nd Law states that the sum of the electromotive forces (emfs) in any closed loop is equal to the sum of potential differences (pds) in that loop.
About Kirchhoff's Second Law
- Also known as the voltage law or loop rule.
- Kirchoff's 2nd Law is based on the conservation of energy.
- Kirchoff's 2nd Law is useful for solving complex circuits with multiple loops.
- The algebraic sum of the products of the Electrical Current|currents]] and the resistances in any closed loop equals the sum of the emfs in that loop.
- Kirchoff's 2nd Law helps in setting up equations to solve for unknown voltages and currents in circuit analysis.
- Kirchoff's 2nd Law is applicable to both DC and AC circuits.
Used in combination with Kirchhoff's first law for comprehensive circuit analysis.
