Choosing node 3 as the datum in Figure 7 below, write down one equation from which you can find \( V_{1} \). Next write down another equation from which you can find \( i_{x} \). From these equations find \( V_{1} \) and \( i_{x} \) Question 8 In the circuit shown below in Figure 8 choose node \( D \) as the datum and regard the region within the dotted line as a 'super-node'. Use NTD analysis to find all the NTD and element voltages. Figure \( 8 . \)
