Determine the Thevenin equivalent voltage ( \( E_{\text {th }} \) ) and Thevenin resistance \( \left(R_{\text {th }}\right) \) for the network below. Hence draw the Thevenin's equivalent circuit looking into terminals a-b and the maximum power which can be transferred to \( \mathrm{RL} \). Show all workings clearly.
