UNIT 09 - Intro to Electricity |
EXPECTATIONS -- Before we start this unit you should:
|
LEARNING TARGETS: → I will be able to show that the source of the electric force is really the repulsive force between electrons → I will be able to demonstrate understanding that electrons always "want" to flow from where there are many to where there are few → I will be able to calculate the electric force (either attractive or repulsive) between two objects with charge given the charge on those objects and the distance between them. → I will be able to demonstrate understanding that the electric force is trillions and trillions and trillions of times stronger than the gravitational force → I will be able to use the charge of an electron to calculate the number of electrons present in 1.0 C of charge as well as the number of electrons passing a fixed point each second → I will be able to use use Ohm's Law (V=IR) to determine voltage, current or resistance in a simple AC circuit given any two of those values. → I will be able to demonstrate understanding that the voltage in a simple DC circuit is at a max right at the source and falls to 0 after passing through (any number of) resistors before returning to the source. |
