I performed practical for finding maximum power transfer theorem on a simple circuit having one load reistance in series to another resistance!!! the practical was performed ok and it gave maximum power transfer when load resistance becomes equal to series resisatnce... but u all know the general curve of power transfer theorem and my readings also gave the perfect curve!!! but the problem is that my teacher says that THE CURVE FOR THE MAXIMUM POWER TRANSFER IS NOT SYMMETRICAL??? i want to ask the reason as he has not told us!!!! so my humble Q is about the unsymmetry of the curve?? any1 plz help me out as I ahve thought a lot but I am not getting the reason behind that!!!!??
