1 The amount of charge passing a point in a given time interval is

2 current

3 Opposite charges ______

4 Attract

5 Like charges _______

6 repel

7 The amount of potential energy stored in a battery is measured in _______

8 volts

9 A material in which electrical charges do not move freely

10 insulator

11 The heating wire in a toaster is low/high resistance

12 high

13 Electrical wiring is low/high resistance

14 low

15 A lightbulb filament is low/high resistance

16 high

17 If the voltage goes up, the current (increases, decreases)

18 increases

19 If the resistance decreases, the current (increases, decreases)

20 increases

21 An accumulation of electrical charges on an insulator is

22 Static electricity

23 In order to separate positive and negative charges, ______ must be added

24 energy

25 Conductors (will/will not) hold a static charge

26 Will not

27 Give 2 examples of an insulator

28 Plastic, glass, wood, rubber

38 induction

39 Method of charging in which electrons are wiped from one object to another

40 friction

41 Material that allows charges to move freely

42 conductor

43 The force between two charged objects

44 Electrical force

45 The region around a charged object where a force is exerted on other objects
