- A **node** is any point in the circuit to which 3+ elements are *directly* connected (i.e., all junctions). - A **node** is any point in the circuit to which 3+ elements are *directly* connected (i.e., all junctions).
- A **supernode** is any connected group in the circuit to which 3+ elements are *directly* connected. - A **supernode** is any connected group in the circuit to which 3+ elements are *directly* connected.
- A **loop** is any closed path of elements. - A **loop** is any closed path of elements.
Kirchhoff's **current law** states that the sum of all current entering a node must be zero, where positive indicates current entrance.
$$\sum i_\text{entering node}=0$$
Kirchoff's **voltage law** states that the sum of all voltage in a **closed loop** must be zero.
$$\sum v_\text{loop}=0$$
