# Physics Tutorials Section 15. Electrodynamics In the Electrodynamics section of Physics we explore Physics Tutorials which guide your through the various skills and learning material within this section. We also provide online Electrodynamics Calculators which allow you to calculate specific Electrodynamics formula in support of the tutorials or to check and verify your own calculations in support of your homework, coursework or thesis.

In this section a number of concepts and quantities such as electric current, charge and current density, direction of current and charges flow, electric resistance and the factors affecting it, are explained. In addition, this section includes concepts like potential difference, electromotive force, electric circuits and components, laws such as Ohm's Law, Kirchhoff Laws, series and parallel combination of cells and resistors, electric power and efficiency, RC circuits, as well as some non-specific concepts such as measuring tools of electric-related quantities, electric current in liquids and gases, electrolysis and Faraday's Law, etc.

In this Electrodynamics section of Physics we cover the following topics:
