A 2. With the “.« (or the reference) terminal of the DMM Voltmeter connected to the selected reference node, directly measure the voltages at nodes “a”, “b”, “c” and “d” (i.e. V., Vs, Ve and Vg, respectively). Use the DMM Voltmeter to directly measure the voltage across resistors, Ri (=Vub), Rz (=Vio) and Ry (=V.a). Measure the current, I using the DMM set up as an Ammeter. From the above measured node voltages (Va, Vi, Ve and Va), calculate the voltages Vb, Vie and Vea. Record all your results in the below Table 4.0. 3.

Imp-lement the circuit in Figure 3.0 on your breadboard using the resistor values as shown. Set the input D.C, source, E = 15V on the power-supply. Nodal Analysis: Refer to the circuit of Figure 3.0a. Use node “d” as the ground reference node, and measure the node voltages V., Vi, and V. with respect to this reference ground. Then measure the branch voltage, Vy across resistor, Rs and the branch current, Iy through resistor, R.. Mesh Analysis: Measure the branch currents I, I, I and Ix, and then use these measured branch currents to determine the values of the mesh currents, I, In and Ic and the branch voltage, Vx.
