For a parallel-plate capacitor, the capacitance is independent of which of the following quantities?

Three capacitors with capacitances $C$, $C$, and $C$ are connected in series. What is the equivalent capacitance of this combination?

A parallel-plate capacitor has plates of area $A$ separated by a distance $d$, filled with Teflon (dielectric constant $k=2.1$). What is the capacitance of the capacitor?

Which of the following is the correct SI unit for capacitance?

A capacitor is being charged in a simple RC circuit by connecting it to a battery at time $t=0$. Which graph best represents the charge $q$ on the positive plate of the capacitor as a function of time $t$?

If three capacitors, each with capacitance $C$, are connected in series, what is the equivalent capacitance of the combination?

When two capacitors are connected in series, which of the following quantities must be the same for both capacitors?

A capacitor of capacitance $C$ is initially uncharged and connected in series with a resistor $R$ and a battery of emf $V$. At time $t=0$, the switch is closed to begin charging the capacitor. What is the charge $q$ on the capacitor immediately after the switch is closed?
