### Electricity

1. 1. Basic Electricity By: Estefania Uribe
2. 2. The basics of Electricity Electrons are what start electricity. Electrons are found in atoms and have negative charge. Every atoms contains one or more electrons.
3. 3. Electricity Electricity is the movement of charged particles from one place to another.
4. 4. For electricity to flow, there has to be something that pushes the electrons. This is called an electromotive force (EMF). A battery or power outlet creates this electromotive force which induces current in a circuit. EMF is measured in volts.
5. 5. Electrical Circuits An electric circuit is a closed path of conductors through which current can flow. Electrical circuits always have a source of electricity such as a battery, a load(a light bulb), and a two wires that carry the electricity between the batter and the load. There are also materials called resistors that are present in circuits that slow down the flow of the current.
6. 6. Series Circuits In a series circuit there is only one path for the electrons to flow. The resistors in a series circuit are connected together in a line. Current flows through each resistor because there are no other paths to follow.
7. 7. Parallel Circuits In a parallel circuit there is more than one continuous path for the electrons to flow. There are several pathways lined up parallel to each other that electricity can pass through. Each pathway has its own resistor. As the current flows through the circuit, the current splits, because current goes through each pathways.
8. 8. Series Circuits If one of the light bulbs is taken out or damaged, the other one will not light up, because the electricity cannot pass through the circuit. Parallel Circuits If one light bulb is taken out or damaged, the other will still light up, because the current can still pass through the other pathways.
9. 9. Examples of Series Circuits Lamps are a series circuit. When the switch is turned on, current will flow to the light bulb. The current can only follow one path. Refrigerators are also series circuits. If they get hotter that the temperature on the thermostat the compressor will turn on dropping the temperature on the inside. Once it gets to the desired temperature the compressor will turn off again.
10. 10. Examples of Parallel Circuits Cities use parallel circuits to power their buildings and homes so that each place can get the same amount of electricity and so if one are goes out the whole city does not. In hour homes, each rooms has its own parallel lighting circuit so, if a light bulb blows, the others don’t.
