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
Penjelasan
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.
