b2/current eletricity

February 7th. Today in physics class we each had around 15 minutes to fill in a worksheet on current electricity. Though hard, it is very interesting and a good review of what I learned in grade 9. We then watched a video of how current electricity works. In the video we learned about electrodes, circuits, direct current and alternating current, and the fact that the amount of electrons passing through 1 point in a DC (direct current) in a period of time will equal the amount of electrons passing through any other point in the circuit within the same amount of time. Near the end of the class Mr. Chung explained to us about the mistake of Ben Franklin. The mistake was his idea of current electricity. Ben originally thought that in a circuit, the positive charges transfer but actually it was the negatively charges that moved. Though wrong we still use this as a measurement because it is now too late to change.
