Statement I: When an external resistor of resistance R (connected across a cell to internal resistance r ) is varied, power consumed by resistance R is maximum when R = r.
Statement II: Power consumed by a resistor of constant resistance R is maximum when current through it is maximum.

A

Statement I is true, Statement II is True, Statement II is a correct explanation for Statement I.

B

Statement I is True, Statement II is True, Statement II is not a correct explanation for Statement I.

C

Statement I is True, Statement II is False.

D

Statement I is False, Statement II is True.

Text Solution

Verified by Experts

The correct Answer is:
B
b. Both statements I and II are true. In Statements I, R is varied
while in Statement II, R is kept constant. Hence, both statements
are independent.
