In parallel combination of n cells, we obtain

more voltage

more current

less voltage

less current

Text Solution

Verified by Experts

The correct Answer is:

In parallel combination of cells the voltage across the terminals is same and resistance is minimum. Therefore from V=IR. The current drawn from cell combination will be more.

In order to obtain a maximum current from a combination of cells, we must join the cells in

parallel combination

series combination

mixed combination

in any of the above combinations depending upon the relative values of external and internal resistance

24 identical cells, each of internal resistance 0.5 Omega , are arranged in a parallel combination of n rows, each row containing m cells in series. The combination is connected across a resistor of 3 Omega . In order to send maximum current through the resistor, we should have

m=12, n=2

m=8, n=3

m=2, n=2

m=3, n=8

To get the maximum current from a parallel combination of n identical cells each of internal resistance r in an external resistance R , when

`R gt gt r`

`R lt lt r`

`R = r`

None of these
