The variable dc current source in the circuit in (Figure 1) is adjusted so that the power developed by the $15\mathrm{A}$ current source is $4300\mathrm{W}$. You want to find the value of $i_{\mathrm{dc}}$. Suppose that $v=560\mathrm{V}$. Would you use the node-voltage or mesh-current method to find $i_{\mathrm{dc}}$ ? The mesh-current method is preferred. The node-voltage method is preferred. Part B Use the method selected in (a) to find $i_{\mathrm{dc}}$. Express your answer to three significant figures and include the appropriate units.
