Study Notes
Kirchhoff's Laws
Kirchhoff's Current Law (KCL)
- States that the sum of all currents entering a node in a circuit is equal to the sum of all currents leaving a node
- Mathematically represented as: ΣI_in = ΣI_out
- Applies to any node in a circuit, where a node is a point where two or more circuit elements meet
- Useful for analyzing complex circuits and determining the current at any point in the circuit
Kirchhoff's Voltage Law (KVL)
- States that the sum of voltage changes around a closed loop in a circuit is equal to zero
- Mathematically represented as: ΣΔV = 0
- Applies to any closed loop in a circuit, allowing for the calculation of voltage drops across circuit elements
- Useful for analyzing circuits with multiple voltage sources and determining the voltage at any point in the circuit
