# Series and Parallel Circuits (Kirchhoff’s Laws, Series and Parallel Formula)

In this post, we investigate qualitatively and quantitatively series and parallel circuits to relate the flow of current through the individual components, the potential differences across those components and the rate of energy conversion by the components to the laws of conservation of charge and energy, as a part of the Prelim Physics course under the module Electricity and Magnetism and sub-part Electric Circuits. This can be achieved by deriving the following relationships:

• \Sigma I = 0 (Kirchhoff’s current law – conservation of charge)
• \Sigma V = 0 (Kirchhoff’s voltage law – conservation of energy)
• R_{Series} = R_{1} + R_{2} + ... + R_{n}

The following videos cover the flow of current through individual components, the potential differences across those components and the rate of energy conversion by the components to the laws of conservation of charge and energy.
