Study Notes
Kirchhoff's Laws of Electrical Network
Kirchhoff's First Law or Kirchhoff's Current Law
- A junction is a point in an electric circuit where two or more conductors are joined together.
- A loop or mesh is a closed conducting path in an electric network.
- A branch is a path that lies between two joints in the network.
- The algebraic sum of current at any junction is always zero, meaning the total current entering a junction is equal to the total current leaving the junction.
- This law can be mathematically represented as: ∑ i = 0, where i is the current in the ith conductor at a junction having n conductors.
