Question

This question centers around two ways to model a load attached to a source.  In both of the figures below, the source is the circuit comprising the 240V voltage source and the 25K and 75K resistors.

Figure 1

 

Figure 2

  1. In Figure 1, suppose we connect (short) a to a′ and b to b′.  Calculate v0.
  2. As an alternative, calculate v0 if the load is connected to the source as in Figure 2.
  3. Comment on the differences between your answers to parts A and B.
