Subject Area

Science

Grade(s)

9, 10, 11, 12

Overview

This episode of Crash Course Phyics delves into the world of AC Circuits (or Alternating Currents). We’ve talked about how they change voltage, which helps transmit electricity over long distances, but there’s so much more to the physics of AC circuitry.

    Science (2015) Grade(s): 09-12 - Physics

    SC15.PHYS.12

    Use the principles of Ohm’s and Kirchhoff’s laws to design, construct, and analyze combination circuits using typical components (e.g., resistors, capacitors, diodes, sources of power).
