1.17 For the circuit shown in Fig. P1.17, find the current in each of the three resistors and the voltage (with respect to ground) at their common node using two methods: (a) Loop Equations: Define branch currents I1 and I2 in R1 and R2, respectively; write two equations; and solve them. (b) Node Equation: Define the node voltage V at the common node; write a single equation; and solve it. Which method do you prefer? Why? Figure P1.17 I1 = 0.75 mA; I2 = 0.5 mA; I3 = 1.25 mA; 2.5 V
