Lecture 28 figures 1 Fig. 28-1: A circuit containing two independent sources and three passive elements. We will use Source Transformations to find v R (t). Fig. 28-1b: The circuit of Fig. 28-1 with source values and passive elements written as phasor quantities. Fig. 28-2: Source transformations and combinations to determine the voltage V R for the circuit of Fig. 28-1. Fig. 28-3: We label the mesh currents on the circuit of Fig. 28-1 to use Mesh Analysis to determine the voltage V R . Fig. 28-4: We label the nodal voltages, relative to the reference node at the bottom, on the circuit of Fig. 28-1 to use Nodal Analysis to determine the voltage V R .

V AB = V oc and I L = 0. We will find V oc as one step in finding the Thévenin equivalent of this network. Fig. 28-5sc: The network of Fig. 28-5 with the output short circuited. I L = I sc and V AB = 0. We will find I sc as one step in finding the Thévenin equivalent of this network. Fig. 28-6: The Thévenin equivalent of the network shown in Fig. 28-5, where V th = (2.6 – j0.8) V and Z th = (26 + j42)Ω. Fig. 28-7: The Norton equivalent of the network shown in Fig. 28-5, where I n = V th / Z th and Z th = (26 + j42)Ω....
