Well atoms have smaller parts
Some negatively charged
Which can move and flow along...we call each one, an electron
...And the flow of these is electricity......We call it a  c-u-R-R- e-n-t
Measured in amps with an ammeter....And check the sound coming through your speaker
And when they (electrons) flow they can make a light bulb glow
But one thing you need to know, for sure,
Is they’ll only flow through a conductor...Like all metals
Some names you’ll learn later....But they will not flow through an insulator...
.....Like glass, rubber or paper....Or any non-metals, alright…
 
Unless it's carbon in the form of graphite.....So how we gonna work it?...
First off, we need a complete circuit
A bulb, wires and something else as well....what we call a cell
And put two of these together, and that’ll be....what we call a battery
But don’t lose me, listen to the rap
Put it all together, make sure there’s no gaps!
 
 
 
 
 
 
 
 
 
 
 
 
 
 
I wanna state this clearly.....
when there’s only one loop we say the circuit’s in series
And there’s rules to this series game
Wherever you put the ammeter the current reading’s the same
And there’s more...... so listen up
Add a cell and the current goes up
But add a bulb clown and the current goes down
And there’s another story to tell......If you set the circuit up in parallel
Adding the extra bulb in a separate loop
So there’s two routes the electrons can take.....so if one bulb was to break
The other stays lit....which would never ever happen in a series circuit
And another thing that isn’t the same
Add that extra bulb and the brightness doesn’t change
Why? Well here’s the scoop...
The current gets higher at the top....and is shared out for each loop
So despite.....Adding a bulb, the light...
...is just as bright...as the one before
So you can have bulbs galore....and they don't get dim
You could say it's a win win....the only problem is that...
The battery is quicker to get flat
And with that, I’ma call it a rap
Keep it flowin’ y’all...I’ll see you on the next track
