The document discusses three questions from a brainstorming session about electrical concepts: 1) What is voltage? 2) What is static electricity and how is it different from current electricity? 3) How can electricity jump through the air? It then provides information about using a voltmeter to measure potential differences across parts of an electrical circuit in volts.

1. From the brainstorm session, three questions come up: 1 Electrical energy is to do with ‘voltage’. What’s that? 2 What is static electricity? Sounds like it’s not like current electricity – that moves! Static sounds as if it stays still. 3 How can electricity jump through the air? It doesn’t do that normally or we’d be in danger from mains sockets. 5 Engage Elicit Explore Explain Elaborate Extend Evaluate
