Questions & Step-by-Step Solutions

Which of the following statements is true about electric current? (2019)
  • Step 1: Understand what electric current is. It is the movement of tiny particles called electrons.
  • Step 2: Know that this movement happens in a material called a conductor, like copper wire.
  • Step 3: Remember that electric current is measured in units called amperes (A).
  • Step 4: Realize that for current to flow, there must be a complete path (circuit) for the electrons to travel.
