Blogpost #21

This morning, my sister and I decided to go and do some homework at Starbucks. After finishing my English homework, I thought I'd do a blogpost. This week, we learned a lot about electricity. Electric potential is measured in volts, electric potential energy is measured in joules, and electric current is measured in amperes. We also learned how to draw schematic diagrams. Sitting in Starbucks, there are lights everywhere, depicted in the picture above. The reason why the lightbulb lights up is because electrons pass energy from a battery or other energy source. The light travels really quickly (at the speed of light), which is why when a person flips a switch, the light goes on instantaneously. Electrons also move, but substantially slower.
