Impedance Matching for Maximum Power Delivery
FIGURE 13.5 Maximizing power delivery.
• If R is infinite, current is zero, therefore no power is transferred out of the battery and none into R either (since the current through R is zero). No power into load.
• If R is 0 Ω, and we somehow pull out 2 A out of the battery, we will get 50 V × 2 A = 100 W out of the battery (max value). Yet none of it gets delivered into R, since R is zero and so the voltage across it is also zero. No power into load.
This is ...
