To maximize the percentage of the power from the emf of a battery that is delivered to a device external to the battery, what should the internal resistance of the battery be?

Respuesta :

Answer:

the internal resistance of the battery be minimized

Explanation:

Because from

P= I²R+I²r

The amount of emf of battery delivered to the external load depends on internal resistance r such that the smaller the r the higher the emf

The internal resistance of the battery be :

-minimized.

Resistance of Battery

The internal resistance of the battery be minimized.

Internal resistance refers to the restriction to the stream of current advertised by the cells and batteries themselves coming about within the era of warm.

Internal resistance is measured in Ohms.

The relationship between inside resistance (r) and emf (e) of cell s given by. e = I (r + R).

The sum of emf of battery conveyed to the outside stack depends on inside resistance r such that the littler the r the higher the emf.
