   1 \begin{problem*}{28.26}
   2 The following equations describe an electric circuit:
   3 \begin{align}
   4   -I_1 (220\U{\Ohm}) + 5.80\U{V} - I_2 (370\U{\Ohm}) &= 0 \\
   5   +I_2 (370\U{\Ohm}) + I_3 (150\U{\Ohm}) - 3.10\U{V} &= 0 \\
   6   I_1 + I_3 - I_2 &= 0
   7 \end{align}
   8 \Part{a} Draw a [possible] diagram of the circuit.  \Part{b}
   9 Calculate the unknowns sand identify the physical meaning of each
  10 unknown.
