Question #200145

Slove this question according to figure 04.

  1. Find the Thevenin equivalent circuit looking from the terminals a-b as shown in Figure 04.
  2. In Figure 04, assume that the load is purely resistive (RL), determine the value of the load resistor RL across terminals a-b for maximum average-power transfer, and calculate the RMS value of the load current when RL is connected between terminals a-b.
  3.  Calculate the complex power drawn by the load when RL is connected between terminals a-b.
Expert's answer

(a) Let current I flow in resistor as no current will flow in resistor due to open.

By KCL at node b

Current in S resistor ,so By KCL in loop


(b) First we have to find Rth (thevenin equivalent seen from b-c node) for this short voltage source and open current source.

As is open so not take part

So, therenin equivalent current for maximum power transfer

(c) As for maximum power

So, maximum power transfer to
