\(E=\cfrac{V}{d^2}.x\) ---(*)
comparing this expression with the normal expression,
\(E=\cfrac{V}{d}\)
we see that \(d\) is replaced with
\(\cfrac{d^2}{x}\)
A comparative graph of the two expressions,
shows that expression (*) has only half the energy. This means only half the energy delivered to the wire is radiated under normal circumstances (superposition). This could mean that, if a material follows instead a material density profile of
Graph of d2/x, d=10 |
such that \(E\) is related to the applied \(V\) given by (*) then we may have close to 100% efficiency for radiated energy.
