| Question | Answer |
|---|---|
| Law of electric charge | states that like charges repel and opposite charges attract |
| Law of electric charge drawing | a light switch, electrical wire |
| Electric Force | The force between two charged objects |
| Electric field | a region around a charged particle that can exert force on another charged particle |
| 3 ways to “Charge It” | Friction, conduction, Induction |
| Conservation of Charge | when you charge objects by and method, no charges are created or destroyed |
| How can a charge be detected | use a electroscope |
| Conductors | a material in which charges can move easily |
| Examples of conductors | metal, tap water, mercury |
| Insulators | a material in which charges cannot move easily |
| Examples of insulators | plastic, rubber, wood |
| Static Electricity | the buildup of electricity on an object |
| Electrical discharge | loss of static electricity as charges move off an object |
| Lightning | a giant electrical charge |
| Lightning Rods | a pointed rod connected to the ground by a wire |
| Grounded | objects that are in contact with the ground |
| Dangerous places when it is lightning include | anything that sticks out, in trees, in open area, |
| Cell | a device that produces an electric current |
| Battery | converts chemical energy into electrical energy and is made of several cells |
| Parts of a battery | electrolyte & electrode |
| Types of Battery Cells | wet cells and dry cells |
| Photocells & examples | the part of a solar panel that converts light into electrical energy |
| Thermocouple | thermal energy can be converted to electrical energy |
| The Atom is how we know what? | Electricity |
| An atom has | Protons, nuetrons, and electrons |
| Proton= | positive charge |
| electrons= | negative charge |
| electrons can | jump from atom to atom |
| electricity is the interaction between | electrons and protons |
| electric current is | the movement of electrons to atoms |
| enery used in the electrons used during discharge | voltage |
| The electural current is measured in | Amps |
| A.C. is when the electrical charge is | changing directions |
| High Voltage wires are made of | aluminum because it is lighter than copper, even though it does not flow electricity as well |
| Circuit | a complete closed path through which electrical charges flow |
| Load | a device that uses electrical energy to do work |
| What do ALL loads do | offer some resistance to electrical currents and cause the electrical energy to change into other forms of energy such as light energy and kinetic energy |
| Explain the relationship that a switch plays in “opening” or “closing” a circuit | it allows the electrical charge to pass through when you close it. |
| Series circuit | a circuit in which all parts are connected in a single loop |
| How many paths are in a series circuit | 1 |
| Explain what happens if one load in the series circuit is malfunctioning | then every load after it will not work |
| Parallel circuit | a circuit in which different loads are located on separate branches |
| Why is this circuit important in the wiring of the lights in a building | it allows each load to function by itself |
| Explain what happens if one load in the circuit is malfunctioning | the others will still turn on |
| Give an example of a parallel circuit in your house | the lights in a hallway |
| explain the causes and dangers of overloading a circuit | it can cause too much electrical energy to go through the circuit which would create thermal energy and start a fire. |
| Explain how a fuse breakers help with circuit safety in your house | a fuse is a thin piece of metal that allows electrical current to pass through, but if there is too much current the strip will become too hot and shrivel up in turn stopping the current. |
| Explain how a circuit breakers help with circuit safety in your house | A circuit breaker is a switch that will automatically open the circuit if there is an unsafe amount of current that is going through the circuit |
