What is ampere? - Electricity Explained - (2)

When you have an electric current it's useful to be able to measure that current. This is done in amps (often using a multimeter). This video explains what an amp (A) (short for ampere) is, which also involves the coulomb (C). The coulomb is the SI standard unit for electric charge, whereas the amp is the SI standard unit for current. 1A equals 1C per 1s (seconds). One coulomb is roughly equivalent to 6.24 quintillion(!) electrons carrying a charge. That's at 1A. Imagine how many electrons pass a certain point when the current is 5000A(!)
