Supposing we have a power generator with internal resistance of 100 ohms and we want to test three different
loads to know which of them has the most efficient power transfer. The loads are as follows: 100 ohms, 400
ohms and 50 ohms.
a. Create a table showing the power consumption of the different loads.
b. What can you conclude about maximum power transfer?
Answers
Explanation:
Efficiency also approaches 100% if the source resistance approaches zero, and 0% if the load resistance approaches zero. In the latter case, all the power is consumed inside the source (unless the source also has no resistance), so the power dissipated in a short circuit is zero.

This circuit below has four "test points” labeled with the letters A, B, C, and D. Assuming the circuit is functioning (light bulb is energized), determine whether or not there will be substantial voltage between the following sets of points: a. Between A and B: voltage or no voltage? b. Between B and C: voltage or no voltage? C. Between C and D: voltage or no voltage? d. Between D and A: voltage or no voltage? e. Between A and C: voltage or no voltage? f. Between D and B: voltage or no voltage? A B D с
