Explain Kirchhoff

Answer :

Kirchhoff’s junction law states that at any junction point in a circuit where the current can divide the sum of currents into the junction is equal to the sum of currents leaving the junction.

Here I1, I4 are currents into the junction whereas I2, I5, I3 are currents out of a junction. So I1 + I4 = I2 + I3 + I5

Kirchhoff’s loop law- The algebraic sum of increases and decreases in potential difference across various components of a closed circuit loop must be zero.

For loop ACDBA

-V2 + I2R2 – I1R1 + V1 = 0

For loop EFDCE

-(11 + 12) R3 –I2R2 + V2 = 0
