Kirchhoff's Voltage Law

The directed sum of the electrical potential differences (voltage drops and rises) around any closed circuit loop is zero (∑ΔV = 0) when expressed under the lumped‑element, quasi‑static assumption; equivalently, the algebraic sum of electromotive forces and voltage drops around a loop equals zero unless a time‑varying magnetic flux links the loop, in which case the integral of the electric field e
