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
Verified Correct Answer: B.
Physical Principles & Numerical Solution
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.
