Static Electricity 3.0 / 5 based on 1 rating ? PhysicsElectricityGCSEOCR Created by: Catherine LewinCreated on: 30-04-13 16:47 What charge does an electron have? A negative charge. 1 of 8 What happens when twon insulating materials are rubbed together (i.e. charges)? One object has a +ve charge due to a loss of electrons and one has a - charge due to a gain of electrons. 2 of 8 What do electrically charge object do to small neutral objects (plus example)? They attract them. For example, a balloon rubbed on a jumper will attract small shreds of paper. 3 of 8 Do the charges move from one object to another? No, the electrons move from one object to the other resulting in a different charge. 4 of 8 What can happen if static builds up? It can lead to a dangerous shock or spark. 5 of 8 How do you safely discharge a charged object? Earth it with a metal strap connected to the ground. 6 of 8 Do electrons flow up or down a strap connected to a negatively charged object? They flow down it (electrons have a -ve charge and same charges repel). 7 of 8 Do electrons flow up or down a strap connected to a positively charge object? They flow up it (electrons have a -ve charge and opposites attract). 8 of 8
