Slide 1 of 3, Electricity flows from a wind turbine to a pylon, to a switch inside a house, to a tv., Wire circuits carry electricity into our homes and schools to power everything we use.

Today, we're going to explore electrical circuits. It's important that you do so with a responsible older person, electricity is powerful and can be dangerous.

Multiwire branch circuits A multiwire branch circuit basically consists of two or more ungrounded conductors that share a neutral. All conductors of a multiwire branch circuit must originate from the ...

University of Washington. "Electrical Circuit Runs Entirely Off Power In Trees." ScienceDaily. ScienceDaily, 9 September 2009. <www.sciencedaily.com / releases / 2009 / 09 / 090908151330.htm>.

Researchers have developed an electric circuit that runs on the power generated by trees. The researchers say it should be enough to power wireless sensors and could also gauge a tree’s health.

What is circuit grounding? Engineers use the word “ground” in every electronic circuit to denote some part of a system or structure that is “ neutral,” or zero potential. Unfortunately, we often think ...

Different models, such as water flowing in a central heating system, can be used to understand electrical circuits. Find out more with BBC Bitesize. For students between the ages of 11 and 14.
