### Electrodynamics Snapshot

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.

### Electrodynamics Calculators

In addition to the Electrodynamics tutorials, 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.

The following Physics Calculators are provided in support of the Electrodynamics tutorials.
