Kirchhoff's laws are two laws that describe the current and voltage in a circuit. The laws are based on the laws of conservation of charge and energy.  Kirchhoff's Current Law (KCL) states that the sum of all currents flowing into a node equals the sum of currents flowing out of the node. Kirchhoff's Voltage Law (KVL) states that the sum of voltages around a loop is zero.  Kirchhoff's Current Law is also known as Kirchhoff's First Law and Kirchhoff's Junction Rule. Kirchhoff's Voltage Law is also known as Kirchhoff's Second Law and Kirchhoff's Loop Rule.  Kirchhoff's laws can be used to... Show more
