Q: What is the effect of a dielectric material on the capacitance of a capacitor? (2023)
Solution: Inserting a dielectric material increases the capacitance of a capacitor by reducing the electric field within it.
Steps: 6
Step 1: Understand what a capacitor is. A capacitor is a device that stores electrical energy.
Step 2: Know what capacitance means. Capacitance is the ability of a capacitor to store charge.
Step 3: Learn about dielectric materials. A dielectric is an insulating material that can be placed between the plates of a capacitor.
Step 4: Recognize the effect of inserting a dielectric. When you insert a dielectric material into a capacitor, it affects the electric field between the plates.
Step 5: Understand how the electric field changes. The dielectric reduces the electric field strength within the capacitor.
Step 6: Connect the effect to capacitance. Because the electric field is reduced, the capacitance of the capacitor increases, allowing it to store more charge.
