9. Draw block diagram above right indicating loop currents. 10. Write initial mesh equations for circuit. 11. Simplify both mesh equations as far as possible. Hint: reduce to two current variables only. For circuit below, find Thevenin equivalent external to element between pts a and \( \mathbf{b} \). 12. Redraw circuit block diagram at above right, with voltage source E shorted to find Zth. 13. Calculate Zth as seen across terminals a-b. 14. With voltage source back in, find Eth (voltage seen across terminals a-b).
