The maximum power transfer occur in a cell when the external resistance is

A.

Twice the internal resistance of the cell

B.

The same as the internal resistance of the cell

C.

Greater than the internal resistance of the cell

D.

Less than the internal resistance of the cell

Correct answer is B

the maximum power transfer theorem states that the maximum power is transferred from a source e.g. cell or battery to its load (external resistance) when the resistance of the load is equal to the internal resistance of the source.
