Teorema sa Maximum Power Transfer
Pangita usab kung adunay voltage source o battery nga may internal resistance nga Ri ug load resistance RL nga gikonekta sa battery. Ang teorema sa maximum power transfer mohatag sa value sa resistance RL aron ang maximum power mahatag gikan sa source padulong sa load. Ang actual nga maximum power, gikan sa source, depende sa value sa load resistance. Mahimong adunay kauban nga confusion, bayran nato kini.
Power delivered to the load resistance,
To find the maximum power, differentiate the above expression with respect to resistance RL and equate it to zero. Thus,
Thus in this case, the maximum power will be transferred to the load when load resistance is just equal to internal resistance of the battery.
Teorema sa maximum power transfer makapahimulos sa complex network as follows-
A resistive load in a resistive network will abstract maximum power when the load resistance is equal to the resistance viewed by the load as it looks back to the network. Actually this is nothing but the resistance presented to the output terminals of the network. This is actually Thevenin equivalent resistance as we explained in Thevenin’s theorem if we consider the whole network as a voltage source. Similarly, if we consider the network as current source, this resistance will be Norton equivalent resistance as we explained in Norton theorem.
