WebKirchhoff's Voltage Law. Kirchhoff's Voltage Law: The sum of voltages around a loop is zero. Kirchhoff's Voltage Law can be written as, \large\displaystyle \sum_n v_n = 0 n∑v n = 0. where n n counts the element voltages around the loop. WebWhen the circuit analysis is complete, one or more of the element voltages around the loop will be negative with respect to its voltage arrow. The signs of the actual voltages always sort themselves out during calculations.
