Question

True and False to a and a voltage of V. (C is the regarding the capacitor charged by à battery. For each statèment below, select True or False. with the capacitor connected to the battery, decreasing d increases U. B After being from the battery, inserting a with K will decrease V with the capacitor connected to the battery, increasing d increases C. B After being D With the capacitor connected to the battery, inserting a dielectric with k will decrease C ed from the battery, inserting a dielectric with k will increase U Tries 0/20 Send Feedback 8

Answer 1

Relations used

$C=\frac{Ak\epsilon_0 }{d}$

$Q=CV$

$U=\frac{1}{2}CV^2=\frac{1}{2}QV=\frac{1}{2}\frac{Q^2}{C}$

A is area of plates.

Also note that V will be constant when battery remains connected, while Q remains constant when battery is disconnected.
