and "Reason" (R) Type question. Use the following Key to choose the appropriate answer. Assertion: When an external resistor of resistance R (connected across a cell of internal resistance r) is varied. Power consumed by resistance R is maximum when R = r Reason: Power consumed by a resistor of constant resistance R is maximum when current through it is maximum: If both and (R) are true, and (R) is the correct explanation of . and (R) are true but (R) is not the correct explanation of . is true but (R) is false. is false but (R) is true.
