Kirchhoff’s Laws:

Kirchhoff’s Laws is divided into two types
i) Kirchhoff’s Current Law (KCL)
ii) Kirchhoff’s Voltage Law (KVL)

Kirchhoff’s Current Law (KCL):

Statement: The total current entering a junction is equal to the total current leaving the junction

Explanation:

Explanation of Kirchhoff’s laws, Electrical Dost

Sign Convention: Incoming currents are taken as positive and outgoing currents as negative.
Mathematically +I1- I2 -I3 +I4 = 0

Kirchhoff’s Voltage Law (KVL):

Statement: The algebraic sum of all voltages around a closed path is zero.

Mathematically, ΣIR + ΣEMF = 0

Explanation:

Sign Convention: Rise in potential is taken as positive and Drop-in potential is taken as negative

Applying KVL to loop ABCDA -I1R1-I2R2+E1 = 0
