Explain what the capacitance of a parallel plate capacitor means.
Three parallel plate capacitors each have a capacitance of $6.0\,\mu\text{F}$. Draw a circuit diagram to show how the capacitors can be connected to give a total capacitance of $9.0\,\mu\text{F}$.
Three parallel plate capacitors each have a capacitance of $6.0\,\mu\text{F}$. Draw a circuit diagram to show how the capacitors can be connected to give a combined capacitance of $4.0\,\mu\text{F}$.
Two capacitors with capacitances $3.0\,\mu\text{F}$ and $2.0\,\mu\text{F}$ are connected in series to a battery of electromotive force (e.m.f.) $8.0\,\text{V}$, as shown in Fig. 6.1.
Calculate the equivalent capacitance of the capacitors.
Use your answer in (i) to determine, for the capacitor of capacitance $3.0\,\mu\text{F}$, the charge on one plate of the capacitor.
Use your answer in (i) to determine, for the capacitor of capacitance $3.0\,\mu\text{F}$, the energy stored in the capacitor.
