Answer 1

B. 7.5 V.

Step-by-step explanation:

For a battery with five dry cells connected in series, the total voltage developed by the battery is the sum of the voltages of each individual cell. Given that each cell has a voltage of 1.5 V, the total voltage developed by the battery is:

1.5

 

V/cell

×

5

 

cells

=

7.5

 

V

.

1.5V/cell×5cells=7.5V.

So, the correct answer is:

OB. 7.5 V.
