Study Notes
Kirchhoff's Second Law
- Kirchhoff's Second Law, also known as Kirchhoff's Voltage Law (KVL), is a fundamental principle in electrical circuit analysis.
- It states that the algebraic sum of the voltages around any closed loop in a circuit must be equal to zero.
- This law is based on the principle of conservation of energy.
- The sum of the voltage drops across the circuit elements must equal the sum of the voltage rises.
- In other words, the total energy supplied by sources must be equal to the total energy consumed by the circuit elements.
- KVL can be used to solve for unknown voltage drops in a circuit by applying the law to different loops and solving the resulting equations.
- It is an essential tool for circuit analysis and design.
