Batteries power much of your daily life. This episode of Crash Course Physics discusses how they work. It also explains how terminal voltage results from the natural internal resistance of every real battery.
In this episode of Crash Course Physics, Dr. Shini walks us through the differences between series and parallel circuits and how that makes Christmas lights work the way they work.
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.
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.
