Kirchhoff's voltage law (KVL): The sum of all the voltages around the loop is equal to zero. v1 + v2 + v3 - v4 = 0. This law is also called Kirchhoff's second law, Kirchhoff's loop (or mesh) rule, and Kirchhoff's second rule. The principle of conservation of energy implies that.

Voltage drop across a diode is ~0.7V

Angle between phases in a 3 phase system is 360/3=120 degrees each.
