See attached file for full problem description. Please solve question number 6 only.
6. Calculate all of the unknown voltages and currents in the above circuit, using either node-voltage, mesh-current, or superposition method. Mark your answers directly on a copy of circuit. In all cases, label the actual direction of current follow and the true polarity of the voltages (i.e., none of your indicated quantities should be negative.)
The solution is comprised of detailed calculations of the currents and voltages of circuit by mesh current method. It can be used a guide on mesh current method of the electric circuits by the students.
