Solve for R. I=E/R+r
\n" ); document.write( "----------
\n" ); document.write( "I=E/R+r
\n" ); document.write( "I*(R + r) = E
\n" ); document.write( "IR + Ir = E
\n" ); document.write( "IR = E - Ir
\n" ); document.write( "R = (E - Ir)/I
\n" ); document.write( "------
\n" ); document.write( "or
\n" ); document.write( "R = E/I - r
\n" ); document.write( " \n" ); document.write( "

\n" );
