Question
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. (C is the capacitance and U is the stored energy.) Answer the following questions regarding the capacitor charged by a battery. For each statement below, select True or False.
True False After being disconnected from the battery, inserting a dielectric with will increase U.
True False After being disconnected from the battery, inserting a dielectric with will decrease V.
True False After being disconnected from the battery, inserting a dielectric with will increase C.
True False After being disconnected from the battery, increasing d increases U.
True False With the capacitor connected to the battery, increasing d increases C.
True False After being disconnected from the battery, increasing d decreases V.
Explanation / Answer
It decreases the U by K times (false)
true it decreases the V by k times
true it increases C by K times
true increases d increases U after disconnecting from battery
false if you increase d then it decrease C
false in last case.
