In this Electrodynamics section of Physics we cover the topics listed in the table below, each topic has a written tutorial (which you can read on your screen, print to read or use a web reader), a video tutorial, revision notes, revision questions and supporting calculators which allow you to check your own computations and calculations.
|15.1||Electric Current. Current Density|
|15.2||Electric Resistance. Combinations of Resistors|
|15.3||Electric Potential Difference (Voltage). Ohm's Law|
|15.4||Electric Circuits. Series and Parallel Circuits. Short Circuits|
|15.6||Electric Power and Efficiency|
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 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.
