Question

In a circuit a cell with internal resistance r is connected to an external resistance R.The condition for
the maximum current that drawn from the cell is
​

Answer 1

Answer:r=0

Explanation:

ANSWER

The maximum current drawn from the cell will be in the case when the external resistance is minimum.

The current in the circuit will be given by:

I= E/R+r

So, the smallest value of denominator will give maximum current.

Therefore, for maximum current, the value of R should be equal to zero.
