## T³: Adventures in Science – Series and Parallel Circuits

There are two basic ways to connect electronic components with two terminals: series and parallel. In this episode, we examine those two types of circuits and show how to calculate equivalent resistance.

## T³: Adventures in Science – Electric Power

Power is the rate of doing work, and for electricity, that means the rate in which energy is converted in a circuit.

## T³: Adventures in Science – Ohm's Law

Let's look at the resistor and how it affects current and voltage in a circuit. Here's a hint: if you know two of either voltage, current or resistance, you can solve for the third.

## T³: Adventures in Science – What is Current?

In this episode, we'll explore how electric current flows through a circuit.

## T³: Adventures in Science – What is Voltage?

Over the next few weeks, we'll explore the basics behind electricity in a series of videos.

## And now for something completely different...
