Kirchhoff's circuit laws are two equalities that deal with the current and potential difference (commonly known as voltage) in the lumped element model of electrical circuits. They were first described in 1845 by German physicist Gustav Kirchhoff. [1] This generalized the work of Georg Ohm and preceded the work of James Clerk Maxwell.
Kirchhoff’s junction rule, also known as Kirchhoff’s current law (KCL), Kirchoff’s first law, Kirchhoff’s point rule, and Kirchhoff’s nodal rule, is an application of the principle of conservation of electric charge. Kirchhoff’s junction rule states that at any junction ( node ) in an electrical circuit, the sum of the currents ...
The circuit has 3 branches, 2 nodes ( A and B) and 2 independent loops. Using Kirchhoffs Current Law, KCL the equations are given as: At node A : I1 + I2 = I3. At node B : I3 = I1 + I2. Using Kirchhoffs Voltage Law, KVL the equations are given as: Loop 1 is given as : 10 = R1 I1 + R3 I3 = 10I1 + 40I3.
Sep 24, 2018 · Gustav Robert Kirchhoff (March 12, 1824–October 17, 1887) was a German physicist. He is best known for developing Kirchhoff’s laws, which quantify the current and voltage in electrical circuits. In addition to Kirchhoff’s laws, Kirchhoff made a number of other fundamental contributions to physics, including work on spectroscopy and ...

Kirchhoff's Voltage Law: The sum of voltages around a loop is zero. Kirchhoff's Voltage Law can be written as, ∑ n v n = 0. where n counts the element voltages around the loop. You can also state Kirchhoff's Voltage Law another way: The sum of voltage rises equals the sum of voltage drops around a loop.
