Kirchhoff's 2nd law
Web2 mrt. 2024 · Define Kirchhoff's Voltage Law. Kirchhoff's Voltage Law states that the algebraic sum of voltages around a closed path or loop in a circuit equals zero. If there are M number of voltages in a loop and V m is the m th voltage, then mathematically, KVL can be written as: M ∑ n=1 v m = 0. WebKirchhoff’s second rule (the loop rule) is an application of conservation of energy. The loop rule is stated in terms of potential, V, rather than potential energy, but the two are related since PE elec = qV. Recall that emf is the potential difference of a …
