1Dielectric Inserted After the Charging Battery Is Disconnected
A parallel-plate capacitor in a school lab has plates of area 0.020 m² separated by 2.0 mm of air. A student charges it to 120 V from a battery, then disconnects the battery and slides in a 2.0 mm thick plastic slab of dielectric constant 3.0 that exactly fills the gap.
