We just learned about what a Anode and Cathode are. We learned a while back that semiconductors are chemicals that do not conduct elec...

We just learned that an electrode is pretty much just a wire that has electricity going through it. If you look closely on a battery, ...

Remember that an electrical conductor is something that electricity goes through very well, and a SuperConductor is really super at hand...

We've learned that if something is kind of a good conductor but not really good, we call it a semiconductor . What about something...

We've learned about how conductivity means how fast electricity goes through something, and that metal is a good conductor, but rubb...

We just learned about what Capacitors are! Let's learn about Electrical conductivity. Electrical conductivity sounds like a coup...

We've now learned about how circuit boards have small things called resistors on them. Another thing you may find on a circuit boa...

Last week we learned about circuit boards how they are just many little eletrical circuits made as small as possible on one little boar...

We learned before about electrical circuits . If you take apart something electronic like an alarm clock, computer or a radio, you will...

We just learned about the Electrical Circuit . Another part of electricity is how light bulbs work. Inside a light bulb there are two wi...

Now that we've learned about voltage , current and resistance , we can try to understand an electrical circuit . Remember what we...

Remember we said before that the three basic parts for most of the electricity that we see every day are: Voltage , current , and resista...
