Physics class is becoming very interesting, especially through this circuits chapter. I am learning about series and parallel, and the different formulas that are applied for each. I have also learned about Ohm's Law (V=IR). At first it was difficult to remember the different formulas for both series and parallel circuits, but after doing many VIR Charts, the work has become a bit simpler. I have learned a few things for both series and parallel circuits
Electric Current (I) is equal all the way through = I1=I2=I3
R = (R1-1 + R2-1 + R3-1)-1
Also, this Kahn Academy video has explained a little more for me!
