Question

Five dry cells each of voltage 1.5 V are connected in series i.e. in assisting manner, What is the overall voltage with this arrangement? *

1) 0V

2)4.5 V

3) 6 V

4) 7.5 V

​

Answer 1

ÁñẞwÉr

The overall voltage with this arrangement is 7.5 Volt.

(D) is correct option.

Explanation:

•Given that,

•Voltage of each cells = 1.5 V

•Number of cells = 5

Suppose the cells are connected in series then the overall voltage will be

√We need to calculate the overall voltage

√Using formula of voltage

V=V 1 +V2+V 3 +V 4 +V 5

•Put the value into the formula

V=1.5+1.5+1.5+1.5+1.5

V=7.5\ VoltV=7.5 Volt

•Hence, The overall voltage with this arrangement is 7.5 volt

Answer 2

The overall voltage of this arrangement is 7.5 V.

Given,

Five dry cells each of voltage 1.5 V are connected in a series.

To Find,

The overall voltage of this arrangement.

Solution,

The formula for calculating the overall voltage when cells are connected in series is

V net = V₁+V₂+...

In this case,

V₁=V₂ =...= 1.5 V

So,

V net = 1.5+1.5+1.5+1.5+1.5

V net = 1.5*5

V net = 7.5 Volts.

Hence, the correct answer is option (d) 7.5 V.
