Mho: … and some say you can still here the blue smoke monster howling in the night!

Minerva: Very spooky Mho. Thank you for sharing it.

Adabot: Hey - how ‘bout we lighten the mood a little bit with some music.  I brought my guitar here.

Minerva: I’ve been working on a little song. Have either of you heard of the scientist, Georg Simon Ohm?

Mho: I haven’t

Minerva: You see, Georg Simon Ohm was experimenting.

And he happened upon something very interesting.

He found that volts and current are related to each other.

But it’s not like they’re cousins, or sisters, or brothers.

It’s a rule, that we now call, Ohm’s Law

You can’t break ohm’s law

Because it’s always true

To find one value

You only need the other two

Say you’re working in a circuit and you need a certain current.

10 milliamps from a 9V supply

How many ohms will give you those amps?

You don’t have to guess or take any chances

Just apply, and rely on

On Ohm’s Law

You can’t break ohm’s law

Because it’s always true

To find one value

You only need the other two

Divide voltage by current … to find the resistance!

Resistance times current … will tell you the volts!

Divide voltage by resistance … to find the current!

And that’s all, that we call - Ohm’s Law

Adabot: So, you really can’t break Ohm’s Law?

Minerva: No, you can’t

Minerva: It is always true

Adabot: and to find one of the values, I just need the other two.

Minerva: You’ve got it!

You can’t break ohm’s law

Because it’s always true

To find one value

You only need the other two

Minerva: Bravo!

Mho: So good!

Adabot: Hey - did you guys hear something?

[Distant howling]

Mho: Uh-ohh …
