Kirchhoff's Current Law (KCL)
Definition
At any node, the sum of currents entering the node equals the sum of currents leaving the node.
Formula
ΣI_in = ΣI_outKirchhoff's Voltage Law (KVL)
Definition
In any closed loop, the algebraic sum of all voltages equals zero.
Formula
ΣV = 0Application Examples
KCL Application:
Node A: I1 + I2 = I3
KVL Application:
Loop: V - I×R1 - I×R2 = 0
