• C)Two capacitors in series always have a lower capacitance than the capacitance of either of the two alone.
• D)Two capacitors in parallel always have a lower capacitance than the capacitance of either of the two alone.
• E)Two capacitors differ only in the dielectric material that fills them.For the same voltage,the one with the higher dielectric constant holds less charge.
