# Summary of Electricity Explained

## 1: Electrical Energy

Electricity is important because we can use it to make so many things work.  That's why we talk about electrical energy.  MORE

## 2. Inside Circuits

We're going to try and picture what goes on inside an electric circuit.  The little black blobs are charges.  MORE

## 3. Atoms and Charge

We'll see that the things that are really flowing inside the wires of electric circuits are called electrons.  MORE

## 4: Complete Circuits

For a circuit to work there must be a complete conducting path from one terminal of the battery to the other.  MORE

## 5. Voltage and Current

We're going to see what voltage and current mean and how they can be measured.  MORE

## 6. Electrical Power

In the first lesson we saw that a bulb is brighter if energy is converted more quickly in it.  MORE

## 7: Resistance & Ohm's law

We're going to find out what happens to the current through a component as the voltage across it changes.  MORE

## 8. Parallel Circuits

We'll see why parallel circuits are so common.  We'll also look at voltage, current, power and effective resistance.  MORE

## 9. Series Circuits

If bulbs are connected in series then there are two problems.  The first is that both bulbs are dim.  MORE

## 10: Domestic Electricity

We’ll look at AC and DC, plugs, earth wires and fuses, and paying for electricity.  MORE
