Voltage Resource

In this video, the person speaking makes clear some very important points about voltage.

• V= Potential Energy/q
• When you are dealing with volts, you are specifically dealing with energy
• and it is energy per charge
• 1 Volt= 1 J/C
• deals with 2 points

I really liked how he said "when we push, from A to B, we are exerting a force through a distance... We are expending energy, and the energy that we expend goes into potential energy and stored as electrical potential energy... There is more Potential Energy at point B then it had at point A." This was really helpful to hear and see him drawing it out. His comparison between gravity and electrical current was very helpful as well (when he is talking about the toaster). I wish he did more with solving problems, though. Pretty helpful, though, with getting the main ideas down.
