Save Da Munz

As you can see, the house is dark. The reason being is because I am trying to save my family some money by saving electricity. I know my parents already pay for my existence, so instead of doing the challenge where I keep the money that is saved on the electricity bill, I'll just let the parentals keep it. They do already pay for my life after all. Some ways that I can reduce electricity usage is by turning the lights off (like in the picture), dropping the water heater temperature 3 degrees, and turning off the AC in my brothers room, they totally over use it. Hopefully my parents will be pleasantly surprised when they see the decrease in electricity usage and decrease in dishing of money to the electricity company.

Drop the Beat Spongebob

This is my battle scarred Spongebob radio. It's okay if you're jealous, I would be too. Anyway, this week in physics we learned about current which is defined as the flow of charge. Charge flows because there is a potential difference. Voltage is a pump for the flow the charge. In things with batteries, such as my Spongebob radio, the batteries act as a pump to move the electrons (flow of the charge). Batteries can be set up as a series, which is the + and - side touching each other, lined up. To find total voltage, you simply add the voltages of each. The formula is Vtota = V1+V2... A parallel series has multiple parts and is when batteries are lined up parallel alternating direction of the + and -. Vtotal = V across each individual path. A parallel series allows for a variety of paths for the flow of the charge. In this case, my cool radio has a parallel series and is my real life connection to physics this week.
