# Capacitors and Dielectrics

## Description

Click-drag
the dielectric blocks, dielectric constants k_{1}=
4.0 and k_{2}
respectively, into the capacitor (charge given in mC and position given in
centimeters). Note: There is a 1-5% intrinsic error in the
calculation of charge. **
**

## Question

What is k_{2}?
You can measure the electric field at any point by click-dragging.**

## Instructor Resources

###### Answer:
2.5. Use the electric field to determine the change in voltage across the
plates. This orientation behaves like a capacitor in parallel. Besides a
detailed calculation, what else can a student determine from looking at the
animation? Well, again, students should be able to determine that **k**_{2 }<** ****k**_{1}.
