David Sang and Graham Jones Solutions for Chapter: Capacitance, Exercise 5: Questions

Calculate the total capacitance of two $100\mu \mathrm{F}$ capacitors connected in parallel.

Calculate the total charge that total capacitance of two $100\mu \mathrm{F}$ capacitors connected in parallel.store when charged to a p.d. of $20 \mathrm{V}$.

A capacitor of capacitance $50\mu \mathrm{F}$ is required, but the only values available to you are $10\mu \mathrm{F},20\mu \mathrm{F}$ and $100\mu \mathrm{F}$ (you may use more than one of each value). How would you achieve the required value by connecting capacitors in parallel? Give at least two answers.
