Saving Electricity


For the past two class days in physics we’ve been learning about saving electricity. My electric bill is around $300. My father works at Hawaiian Electric Company as a machinist. After talking with him about conserving electricity and lowering the electric bill, he told me several ways that our family could help to lower the bill. Putting a timer on the water heater, taking cold showers, turning the shower off when you soap yourself, unplugging things (like fans) you don’t use constantly, hanging clothes instead of drying them and using a fan instead of the air conditioner are some ways that you can save electricity, along with lowering the amount of money my parents pay for the electricity bill.

Circuts


There are two types of circuits possible. One is a DC Circuit and the other is an AC Circuit. A DC Circuit is a direct current in which the charge flows one way. For example my Kindle is a DC Circuit. When I charge it, the charges from the wall go into my phone. My phone doesn’t give charges back to the wall, making it a DC Circuit. An AC Circuit is an alternating current. A conventional current is the direction in which the positive charges flow. I also learned the reason why the band ACDC got its name and why they have a lightning bolt on all their merchandise.
