So what is an amp? A quick recap, metals like copper have electrons that flow freely throughout 00:00:00
the material, from atom to atom, even at room temperatures. And, as explained in the first 00:00:06
video with the marble analogy, when electrons move from atom to atom, they displace other 00:00:13
electrons already there, which then push other electrons, and so on, and so forth. These 00:00:18
properties make metals excellent conductors. There are billions upon billions of electrons 00:00:25
in even a single, simple copper wire. Now, when creating an electric current, it's useful 00:00:31
to be able to measure this current. This is measured in amps, or ampere. One amp equals 00:00:38
one coulomb per second. Ampere is the base unit of electric current, or how many electrons 00:00:45
flow past a single point every second. One coulomb is the unit of electric charge, which 00:00:52
is carried by approximately 6.24 x 10-18 electrons. That's 6.24 quintillion electrons flowing 00:00:59
past a certain point every second. Two amps is double that number of electrons flowing 00:01:11
past every second. 0.5 amps, or 500 milliamperes, is half that number of electrons per second. 00:01:17
To put it into perspective, the adapter of my laptop requires an electric current of 00:01:26
one amp, while the current in a lightning strike can vary from 5,000 to 50,000 amperes, 00:01:30
depending on the strength of the storm. 00:01:37
