Which characterization accurately describes BOTH parallel lights and series lights? A) They both pass electricity from light to light.

B) They both attach bulbs to their own circuit.

C) They both return electricity to its power source.

D) They both prevent bulbs from becoming defective.

Adielectric-filled parallel-plate capacitor has plate area a = 30.0 cm2 , plate separation d = 9.00 mm and dielectric constant k = 3.00. the capacitor is connected to a battery that creates a constant voltage v = 15.0 v . throughout the problem, use ϵ0 = 8.85x10-12 c2/n.m2 . find the energy u1 of the dielectric-filled capacitor.
