Move on to Capacitors and RE-write the definition from the green book

What a capacitor is, what it does and how it can be used.

Define capacitance What capacitance is, how it is defined and the formula for it

BUILD the capacitor construction formula – including the dielectric constant and the absolute permittivity of free space

What the bits of the equation are, what they mean and where they come from

Do a couple of examples from the red book
