Capacitors and Kirchhoff: Crash Course Physics #31


Content Source:

Type: Audio/Video


What happens when there are multiple batteries connected in parallel? What happens when we add capacitors into the mix with resistors in our DC circuits? In this video, we’ll encounter junctions, loops, and capacitors.

Content Standard(s):
SC2015 (2015)
Grade: 9-12
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).
