Question

In a series combination of cells the effective internal resistance will ....
a) remains the same b) decrease
c] increase
d None of these.​

Answer 1

Answer:

increase is the right answer

Answer 2

In a series combination of cells the effective internal resistance will c) increase.

• A cell is said to be connected in series when the successive cells are connected to one another such that the positive terminal of the previous cell is connected to the negative terminal of the succeeding cell.
• When cells are connected in series, their internal resistances also get connected in series.
• We know that in a series arrangement, the net effective resistance is greater than the individual resistances.
• Hence, the effective internal resistance will increase.
