Questions & Step-by-Step Solutions
What is the effect of a dielectric material on the electric field inside a capacitor?
Correct Answer: Dielectric material decreases the electric field inside a capacitor.
Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy in an electric field.
Step 2: Know what a dielectric material is. A dielectric is an insulating material that can be placed between the plates of a capacitor.
Step 3: Recognize that when a dielectric is inserted into a capacitor, it affects the electric field between the plates.
Step 4: Learn about polarization. When the dielectric is inserted, it becomes polarized, meaning it creates small electric dipoles that align with the electric field.
Step 5: Understand that this polarization reduces the overall electric field inside the capacitor because the dipoles create an opposing field.
Step 6: Conclude that the effect of inserting a dielectric material is to decrease the electric field inside the capacitor.
