Power balance

We make the equations to determine the power of the receiver:

ΣPpr = Σ I² • R

Build equations for determining the power source:

ΣPist = Σ E • I

The balance converges provided that the power and receiver power equations are equal, i.e .:

ΣPpr = ΣPist

The balance is considered converged if the error of non-convergence is no more than 2%
