The circuit shown in Figure P 5.3-3 has two inputs, \(v_s\) and \(i_s\), and one output, \(i_o\). The output is related to the inputs by the equation

                                                       \(i_o = ai_s + bv_s\)

Given the following two facts:

     The output is \(i_o = 0.45\) A when the inputs are \(i_s = 0.25\) A and \(v_s = 15\) V

and

    The output is \(i_o = 0.30\) A when the inputs are \(i_s = 0.50\) A and \(v_s = 0\) V

Determine the values of the constants a and b and the values of the resistances are \(R_1\) and \(R_2\).
