Answer to Question #218484 in Electric Circuits for Ojsmart

Question

State Kirchhoff's law and identify the conservation associated with each

Answer 1

Kirchhoff’s first law- it states that the sum of current entering to the junction is equal to sum of current leaving the junction.

i.e., $∑I=0$

, where I denote the current.

Kirchhoff’s second law- It states that the algebraic sum of potential drops in a closed circuit is zero.

i.e., $∑IR=0$

 where I and R are the current and the resistance.

The first law is based on charge conservation.

The second law is based on conservation of energy.
