Question

question 20 of 20 : select the best answer for the question. 20. a battery consists of five dry cells connected in series. if the voltage developed by each cell is 1.5 v, the total voltage developed by the battery is
a. 7.5 v.
b. 0.3 v.
c. 1.5 v.
d. 5.0 v.
mark for review (will be highlighted on the review page)

Explanation:

Step1: Recall series voltage rule

In series, total voltage \( V_{total} = n \times V_{cell} \), where \( n \) is number of cells, \( V_{cell} \) is voltage per cell.

Step2: Substitute values

\( n = 5 \), \( V_{cell} = 1.5 \, V \). So \( V_{total} = 5 \times 1.5 \, V \).

Step3: Calculate

\( 5 \times 1.5 = 7.5 \, V \).

Answer:

A. 7.5 V
