1 Electricity MR. BANKS 8 TH GRADE SCIENCE

2 Electric charges Atoms and molecules can have electrical charges. These are caused by electrons and protons. Electrons are negatively charged. Protons are positively charged.

3 Electric charges Like magnets, electric charges interact with one another. Also like magnets, like charges repel each other and opposite charges attract one another. The attraction and repulsion between electric charges is known as electric force.

4 Electric charges Electric field the region around a charged object where the objects electric force interacts with other electric charges. Electric field lines are drawn going away from positive charges and towards negative charges.

5 Electric charges Unlike magnets, electric charges can exist on their own. A material does not have to have a corresponding positive charge when it has a negative charge and vice versa.

6 Electric charges Electric fields interact with one another in much the same way as the poles of two magnets interact. Likes repel, opposites attract

7 Static electricity Most objects have no overall charge. Things can become charged through the transfer of electrons from one object to another. Protons are stuck in the atoms that they make up, but electrons can move around. Things that lose electrons become positively charged. Things that gain electrons become negatively charged.

8 Static electricity Static electricity is a simple electric charge that is built up on an object and does not flow. In static electricity, charges build up on an object, but they do not flow (move) continuously.

9 Transferring static charge Static charges can be transferred between objects in three ways. Friction, conduction, and induction. Friction transfer When two uncharged objects are rubbed together some electrons may move between objects.

10 Transferring static charge Conduction when a charged object touches an uncharged object electrons may be transferred from one to another.

11 Transferring static charge Induction The movement of charges within something by bringing a charged object close to it.

12 Static discharge Static discharge When a negatively charged object and a positively charged object are brought together electrons transfer until the two objects have the same overall charge. Often static discharge produces a spark.

13 Static discharge Lightning is a great example of static discharge on a large scale.

15 Static electricity Why is static electricity static? Can we use static electricity to power electric devices? Lightning contains millions of volts of electricity, can we use it? No Why not?

16 Electric current To power electric devices we need a different type of electricity. We need electricity that replaces itself as it is used. We need electricity that flows. Electric current is the continuous flow of electric charges through a material.

17 Electric current Think of electricity like water, if it s sitting still it can t do much, but if it is flowing it will be able to do work.

18 Measuring current The amount of electric charge that passes through a wire in a given time is the rate of electric current. The unit is the ampere or amp for short. An amp is the amount of charge that passes a point each second. Andre Ampere

19 Electric Circuits Electric current cannot just exist in a material. It must have a path to follow (like a wire). Electric current requires the ability to flow from one place to another in an unbroken path. If there is a break in the path at any point there can be no flow of electricity. An electric circuit is a complete unbroken path through which electric charges can flow.

20 Electric circuits Electric circuits must also exist as a loop. Where there is a connection that goes out from the energy source and returns without being broken. They cant just go to a destination and stop.

21 Conductors and insulators Does electricity flow equally in all materials? NO A conductor is a material that transfers electric charge well. Electricity flows easily through a conductor. An insulator is a material that does not transfer electric charge well. Electricity has trouble flowing through an insulator.

22 Conductors Metals are generally good conductors of electricity. Silver, copper, aluminum, and iron are all good conductors. Materials that are good conductors hold on to their electrons loosely therefore the electrons are able to move easily.

23 Conductors Electrons are already present in conductors, but in order to move they need to be forced to. When an electric current is hooked up, one end of the wire pushes the electrons and the other end of the wire pulls electrons. This forces electrons to jump from one atom to the next.

24 Insulators Rubber, glass, sand, plastic, and wood are all good insulators. In insulators, the electrons are bond tightly to their atoms and are unable to easily break free. Therefore electricity cannot easily flow through them. Insulators can still conduct electricity, but they just don t do it as well. You can still get shocked through an insulator.

25 Voltage If I make a loop of wire, will electricity flow all by itself? No Much like a physical thing, electricity must have a push or pull in order to move. This push and pull is accomplished by having a difference in electrical potential energy from one end of the circuit to the other.

26 Voltage Voltage is the difference in potential energy between two places in a circuit. Voltage is what creates the current in a circuit. Think of it as how hard the charge is being pushed through the wire. The unit for voltage is the volt (V).

27 Voltage sources A device that creates an electrical potential difference in an electric circuit. Batteries Electric generators

28 Resistance Current depends on more than voltage. Resistance is the measure of how difficult it is for charges to flow through a material. The higher the resistance, the less current (flow) there is for a given voltage. The unit of resistance is the ohm (Ω).

29 Resistance Multiple factors contribute to resistance The material of the wire Conductors do not have much resistance Insulators have a higher resistance since electrical charge has a more difficult time moving through them.

30 Resistance Length Longer wires of the same material have more resistance than short ones. Diameter Smaller diameter wires have more resistance than large diameter ones. Think about water moving through a pipe.

31 Resistance Temperature Resistance increases as the temperature increases in most materials.

32 Resistance

33 The path of least resistance When given the opportunity to pass down two paths, electric current will always choose the one with the lower level of resistance. This can lead to a short circuit.
