ok, some are going to say "what the hell?" etc but Im confident we got smart people on board like Lee.
If a resistor of R ohms is connected across a battery of E volts with internal resistance of r ohms, then the power (in watts) in the external resistor is
P = (E² R) / (R + r)²
If E and r are fixed but R varies, what is the maximum value of the power?
Its application of differentiation. Please
