Statement I : In the circuit in `Fig. 7.46`, both cells are ideal and of fixed emf, the resistor `R_(1)` has fixed resistance and the resistance of resistor `R_(2)` can be varied ( but `R_(2)` is always non zero). Then the electric power delivered to the resistor of resistance `R_(1)` is independent of the value of resistance `R_(2)`.
Statement II: If potential difference across a fixed resistance is unchanged , the poweer delivered to the resistor remains constant.

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 is False.

D

Statement I is False, Statement II is True.

Text Solution

Verified by Experts

The correct Answer is:
A
The potential difference across resistance `R_(1)` is always `|E_(1) - E_(2)|`. Hence , assertion and reason are true and the reason is the correct explanation of the assertion.
