📘 Introduction
Kirchhoff’s Laws are fundamental rules used to analyze electrical circuits. These laws help us understand how current and voltage behave in a network.
⚡ Kirchhoff’s Current Law (KCL)
Statement: The total current entering a node is equal to the total current leaving the node.
Formula: ∑I(in) = ∑I(out)
Example: If 5A enters and splits into 2A and 3A, the law is satisfied.
🔋 Kirchhoff’s Voltage Law (KVL)
Statement: The sum of voltages in a closed loop is zero.
Formula: ∑V = 0
Example: Battery = 10V, drops = 6V + 4V → Total = 0
