Series: Shedding Light on Electricity


Electric Circuits

Electric Circuits

In the second episode, we examine how lights, switches, and other electrical devices are all connected either in "series" or in "parallel" with each other. How do they wire up the lights in your house so that in some rooms the light switch turns...Show More
Electric Currents

Electric Currents

In episode three, we take a look at what electric current is (it's basically the flow of electrons through a wire) and at how electric current is measured. We then examine the different ways that electric current flows in series and parallel...Show More
Electrical Safety

Electrical Safety

In "Electrical Safety", we first look at the dangers of electric shocks by actually demonstrating an electric shock. We then look at the safety features built into our homes and electrical devices that keep us safe from electric shocks.
Sources of Electricity

Sources of Electricity

In 'Sources of Electricity', we take a detailed look at where our electricity comes from: thermal and hydroelectric power stations, wind farms, and solar farms. We alo examine the advantages and disadvantages of these sources of electricity.
Voltage, Current, and Resistance

Voltage, Current, and Resistance

In this episode, we look at how electrical equipment is designed to use the right amount of current for the voltage supply that it's designed for. After a brief recap on electric current, we look at what voltage is and how it is measured. we then...Show More
