Work through problems with immediate feedback

Recall / Warm-Up

When a dielectric material is inserted between the plates of a charged capacitor (with the plates disconnected from any battery), what happens to the voltage across the plates?

The voltage decreases because the dielectric reduces the electric field.

The voltage increases because the dielectric increases the capacitance.

The voltage stays the same because charge is conserved.

The voltage increases because the dielectric strengthens the field.
