In this week's Gizmodo University: Discover Electronics, we're diving headfirst into the principle theories of electronics. The second of four classes in this series, "Volts, Amps, and Ohms" is presented in conjunction with Sparkle Labs.

Good morning class, today we will be building off of last week's introduction to electronics theory. If you missed last class, please take a moment and review the last lesson, paying special attention to Chapter 5. Right then, let's get started.

### Chapter 1: The Resistor

So, now that we've got the basics of resistance down and can recite that handy mnemonic from memory (Big Boys Race Our Young Girls But Violet the Great Wins). we'll move onto Dividing Voltage. If you think you've got a better mnemonic, tell us in Comments!

### Chapter 2: Voltage Divider

Take some time to experiment with your new voltage divider and familiarize yourself thoroughly with it because we're taking this concept a step further with our discussion of circuits in series and parallel.

### Chapter 3: Series / Parallel

Remember, two resistors in series will increase the resistance by R = R1+R2, two resistors in parallel will decrease resistance by 1/R = 1/R1 + 1/R2. If you are having trouble understanding the math or concepts, feel free to ask your Sparkle Labs TA in the Comments section below!

### Chapter 4: Ohm's Law
