Rayliegh's Theorem

Rayliegh's Theorem is derived from the equation for Energy

• $W=\underset{-\mathrm{\infty }}{\overset{\mathrm{\infty }}{\int }}p(t)dt$

If we assume that the circuit is a Thevin equavalent then $p(t)=\frac{x^2(t)}{R_L}$ for matters of simplicity we can assume $R_L=1\mathrm{\Omega }$
