What is an Amp?

Introduction to Electric Current

  • This video serves as a follow-up to the creator's previous discussion on electricity, providing foundational knowledge about electric current.
  • Metals like copper allow electrons to flow freely from atom to atom, which is essential for conducting electricity.

Understanding Amperes

  • An ampere (amp) measures electric current; specifically, it quantifies how many electrons pass a point per second.
  • 1 amp equals 1 coulomb per second, where 1 coulomb represents approximately 6.24 quintillion electrons flowing past a point every second.

Practical Examples of Current Measurement

  • The adapter for a laptop typically requires an electric current of 1 amp.
  • In contrast, lightning strikes can produce currents ranging from 5,000 to 50,000 amperes depending on storm intensity.

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(!)
