You have two identical capacitors and an external potential source. a) compare the total energy stored in the capacitors when they are connected to the applied potential in series and in parallel. u(parallel)/u(series) =? b) compare the maximum amount of charge stored in each case. q(parallel)/q(series) =? c) energy storage in a capacitor can be limited by the maximum electric field between the plates. what is the ratio of the electric field for the series and parallel combinations? e(parallel)/e(series) =?

Charge is distributed along the entire x-axis with uniform density λ. how much work does the electric field of this charge distribution do on an electron that moves along the y-axis from y = a to y = b? (use the following as necessary: a, b, ε0, λ, and q for the charge on an electron.)

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
