Question

A battery of fixed emf E and internal resistance r is connected to a variable external resistor R. what would be the relation between R and r when maximum power is delivered.
Options
A R=2r
B R=r
Correct Answer
C R=r²
D R=√r
Correct Answer

Option B is the correct answer.

Detailed Explanation

According to the maximum power transfer theorem, maximum power is delivered from a source to a load when the load resistance (external resistor R) is equal to the internal resistance (r) of the source.

Hint

Remember the Maximum Power Transfer Theorem for DC circuits.
