What is Kirchhoff's Voltage Law (KVL)?
Kirchhoff's Voltage Law is one of the fundamental principles used for circuit analysis. It is based on the principle of conservation of energy.
The algebraic sum of all the voltages around any closed loop in a circuit is equal to zero.
This means that for any complete loop in a circuit, the sum of the voltage rises (from sources like batteries) must equal the sum of the voltage drops (across components like resistors). This tool helps you visualize this principle by generating random circuits and showing the full KVL calculation.
