The maximum power transfer occur in a cell when the external resistance is
- Twice the internal resistance of the cell
-
The same as the internal resistance of the cell
- Greater than the internal resistance of the cell
- Less than the internal resistance of the cell
The correct answer is: B
Explanation
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.
