Before we watch the video about Nuclear Energy, let’s watch this video about how electricity get generated and reach our home.
And now, let’s study about nuclear energy.

Here is a good video to recap what you have learnt in school about series and parallel circuits.
You can also download the simulator used in the video (Circuit Construction Kit) from this site: http://phet.colorado.edu/en/simulation/legacy/circuit-construction-kit-dc
The above video shows the current and voltage drop in series and parallel circuits.
Now, let’s watch this video showing an experiment on resistance in series and parallel circuits.
A good video introducing resistor.
Pre-requisite: watched the videos in previous post “What is Voltage“.
I like this video explaining what is voltage, what is current, what is resistance, and what is actually behind the scene of a battery. Basically he is explaining the Ohm’s law.
And the following video clears the confusion of which way current is actually flowing, from positive side of the battery towards the negative? or from negative side towards positive ?
