... 5. Two parallel plate capacitors, C1=20 µF and C2=10 µF, respectively, are connected in series to a battery. Which statement is true? For capacitors in series, the magnitude of the charge on each plate must be the same: Q1 = Q2. The reason is that the conductor between the two capacitors must have z ...

Problem 5 - Electrostatics of Phospholipids in the Bilayer Phosphatydilserine is a phospholipid with a negatively charged headgroup (Q = −1.6 × 10−19 C) that often finds itself on the cytosilic side of the lipid bilayer. Although most phospholipids in the bilayers are not charged, we can use a charg ...
