Work through problems with immediate feedback

Recall / Warm-Up

A parallel-plate capacitor is connected to a 12 V battery. The voltage across the capacitor is:

12 V, equal to the battery voltage.

Less than 12 V, because the capacitor uses up some voltage.

More than 12 V, because the capacitor amplifies voltage.

Zero, because the capacitor blocks DC.
