Electricity is important because without it life as we know it would be uncomfortable. We wouldn’t have a lot of the technology we have now, such as cell phones, computers, air conditioners, stoves, and many other gadgets. Imagine life without your cell phone, computers, or even light. Does that seem like a comfortable life? No? Well it gets worse. Imagine life with no refrigerators, water heaters, or television. How does life seem now? Okay, this proves my point that electricity is very important because without electricity, that is exactly how life would be.

The three components that make up Ohm’s Law are: the Voltage, measured in volts, Current, measured in amps, and the Resistance, measured in ohms. The way that Ohm’s Law works is the voltage(V) equals the product of the electrical current(I) and the resistance(R) working in an electrical current. V= I R
4
Voltage The source of the waterfall represents the voltage. The force of the waterfall is gravity because that’s the element that is pushing the water down just like how the voltage pushes the current through the circuit.
5
Resistance Just like the rocks in the water, the resistors in the circuit impede the flow of the current and provide obstacles for the current to go through.
6
Current Just like the current in the circuit, the water in the waterfall flows through and the cracks and crevices all the way a desired destination.

Conductors are used in electricity to allow charges move easily. For instance, if you are working on an electric track and you need to connect two pieces of materials that are electrically charged, you could use a metal as a conductor. Conductors Conductors Insulators Electric Charge
8
Insulators Insulators are materials that do not allow electric charge to flow through freely, such as rubber, glass, and wood. An electrician has to use an insulator to protect himself against electric charges that will try to flow to his body, and makes electrical wires safe to touch. Conductors Insulators Electric Charge

Electrostatics is the study of electric charges at rest. In the19th century when physicist classified forces in 3 groups: Gravitational, electric, and magnetic In 20th century, however, physicist added two more forces which are strong and weak forces, but then found links to narrow it back down to only two: gravitational and electromagnetic.
10
Electrons(-) Negative charge have the smallest negative charge Neutron Neutral charge Protons(+) Positive charge Carry the smallest positive charge About 2,000 times more the size of electrons Opposites Attract Like Charges Repel Protons, which have a positive charge and electrons, which have a negative charge attract together because… well, because opposites attract of course.
11
All of the charges arrange themselves to form an atom. The proton resides in the nucleus with the neutron. The electron resides outside the nucleus to maintain balance between the positive and negative charges. The atom resembles a familiar form, Saturn’s rings.
12
Parallel CircuitSeries Circuit Many paths for electricity1 path for electricity If one light goes out, the other lights can still work.If one light goes out, the other lights will go out too. Best example of a parallel circuit is track lightings.Best example of a series circuit is Christmas lights.
13
From how it began to what times of charges cause it to the types of circuits that are used in our everyday buildings, we can agree that electricity is very important and has many intricate details. It’s important to understand the inner workings of electricity because as society progresses one thing that people will always need is electricity and jobs that deal with electricity will flourish. Understanding electricity is important because someone will need to invent the next best thing and it will be the person who knows electricity and how to maneuver and manipulate it to invent something that will change society.
