which statements are true for two oppositely charged, isolated parallel plates: C=capacitance, U=stored energy, (Q and -Q =charged on the plates). Note: isolated plates can not lose their charge.
a. when the distance is doubled, U increase.
b. inserting a dielectric increases Q
c. when the distance is halved, Q stays the same.
d. when the distance is doubled, C increases
e. insertng a dielectric increases C
f. increasing the distance increases the Electric Field
g. inserting a dielectric decreases U
by using these equations: C=Eo (a/d) , Q=CV, and U=1/2 QV, Q^2/2C
i came up with TFTTTFT, but its not right anyone has any idea of what i might of done wrong?
