(a) Junction: It is a point where two or more conductors are connected to source and current gets distributed at that point.
Loop: Loop is a closed path of an electric circuit.
(b) Kirchhoff's First Law or Junction Rule. It states that the algebraic sum of currents meeting at a point is zero.
This law is also called Kirchhoff’s current law. Kirchhoff's Second Law or Loop Rule It states that in a closed electric circuit, the algebraic sum of e.m.f.’s is equal to the algebraic sum of the products of the resistance and the currents flowing through them.
This law may be called Kirchhoff’s Voltage Law.
