SUMMARY
Adding a dielectric to a capacitor increases its charge storage capacity due to the dielectric's ability to weaken the electric field within the capacitor. This weakening occurs as the dielectric material polarizes, aligning its dipoles with the electric field, which effectively reduces the field strength. Consequently, the capacitor can store more charge for the same voltage, enhancing its overall capacitance. The phenomenon is rooted in the interaction between the dielectric's dipoles and the electric field generated by the capacitor's plates.
