Circuit Analysis

The current and voltage of components and Nodes within a circuit can be identified using Kirchhoff's Laws and Ohm's Law

Current Through Parallel Resistors

Because of KCL, the sum current in into a system of resistors is the same a the sum current out of the system

Current of a resistor in parallel
$$ i_{a}=i_{\text{total}} \frac{R_{\text{parasitic}}}{R_{a}} $$
