Current is

Current is

• A. A static charge
• B. A flow of electric charge
• C. A magnetic field
• D. A difference in voltage with no movement

Answer: (B)

Current is the flow of electric charge. It represents how much charge passes a point in a circuit each second, and it occurs when there is a complete path and a driving force (voltage) causing charges to move. Static charge sits still, so it doesn’t constitute current. A magnetic field can arise from moving charges, but the field itself isn’t the current. And a difference in voltage without any movement is just a potential difference, not current. In a conductor, electrons drift and carry charge; conventional current is taken as the direction positive charges would move, even though actual electrons move the opposite way.
