What is the relationship between the AC current through a capacitor and the voltage across a capacitor?

Answer choices for E5B09
Why this wins

The key fact is Current leads voltage by 90 degrees. Match that fact to the exact condition in the question; the other choices describe a different rule, band, component, or operating situation.

Memory hook: Capacitors store energy in an electric field.

E = I × R
