Analyse the circuit in Figure 2 using nodal voltage analysis. The steps of applying nodal analysis are listed in Unit 2 Section 4. The reference node and the labelling of voltages and currents have been provided to you. You should use these node names and branch currents in your analysis. (a) Express the currents I to Is in the form (Vx - Vy)/R as listed in the steps of the nodal analysis. (b) At node 2 and node 3, apply Kirchoff's current law to obtain two simultaneous equations. (c) Using your results in (b), solve the nodal voltages V and V3. (d) Hence, find the current I5. Vs = 5V V Y I V |R1 1k 2k 13 R3 12 R 2k 14 RA 1k V3 15 R5 3k
