While the video below is a bit longer than most of the resources I use, I think the speaker really explains the concept of current in relation to voltage and resistance well. He speaks slowly and does not try to cram too much information into a two minute video, like some other sources tend to do. I think this video is worth the watch and definitely a helpful source!

Current
Current refers to the flow of electrons in a circuit. Current is caused by voltage, or potential energy difference. Current and voltage are directly related, while current and resistance are inversely related. Resistance is what slows down or weakens a current. This can all be summed up in Ohm's Law: Current = Voltage / Resistance. The greater the voltage, the stronger the current, the greater the resistance, the weaker the current.
