case 1
A parallel plate capacitor with plate separation d is connected to a battery. The capacitor is fully charged to Q Coulombs and a voltage of V volts. Let C be the capacitance and U the stored energy. Select True or False for each statement. Û With the capacitor connected to the battery, inserting a dielectric with x > 1 will decrease Q. À After being disconnected from the battery, increasing d increases U. With the capacitor connected to the battery, decreasing d increases U. Û After being disconnected from the battery, decreasing d increases C. Û After being disconnected from the battery, increasing d decreases V. With the capacitor connected to the battery, inserting a dielectric with x> 1 will decrease U.
Plates that are isolated cannot lose their charge. Which statements below are True or False for two oppositely charged, isolated parallel plates? (Let C = capacitance, U = stored energy, +Q and -Q be the respective charges on the plates). Û When the distance is halved, Q stays the same. © When the distance is doubled, C increases. Û When the distance is doubled, U increases. Inserting a dielectric decreases U. Inserting a dielectric increases Q. Increasing the distance increases the electric field. Û Inserting a dielectric increases C.
