Question
I have no idea what I have wrong. I keep reading the notes, and I swear this is correct.
A parallel plate capacitor with plate separation d is connected to a battery. The capacitor is fully ch the capacitance and U is the stored energy.) Answer the following questions regarding the capácit below, select True or False. FalseWith the capacitor connected to the battery, inserting a dielectric with K will decrease U. True With the capacitor connected to the battery, decreasing d decreases Q False After being disconnected from the battery, inserting a dielectric with K will decrease v. True After being disconnected from the battery, decreasing d increases U False After being disconnected from the battery, decreasing d decreases C. True With the capacitor connected to the battery, inserting a dielectric with K will decrease C.Explanation / Answer
three options you have selected are wrong.
3rd option is true because inserting dielectric increases C and V = q/C decreases
4th option is false because decreasing d will increase C so U = 1/2 Q^2/C decrease U
6th option is false inserting dieletric always increase C and it is independent of battery connected or not
other options are filled right
