What is Electricity Part 5: What is an Ampere? How to Calculate Charge from Current

In this video we continue our series looking into the nature of electricity, having defined the coulomb in a previous video we now look at how that relates to the definition of an Ampere or Amp. We also look at some examples of calculations that show the connections between current and charge.
