Question

Four cells each of 1.5 V are connected in series. What is the total voltage of battery?​

Answer 1

Answer:

6 Volts

Explanation:

As we know that in series

           $R_{eq}$ = $R_{1} +R_{2} +R_{3}$

                 =  1.5 + 1.5 + 1.5 + 1.5

                =  6 volt

Answer 2

Answer:

The total voltage of battery is 6 Volts.

Explanation:

If we go around the circuit in the clockwise direction.

Then by kirchhoff's voltage law which states that,

→ effective voltage in a circuit is zero.

i.e.  1.5 + 1.5 + 1.5 + 1.5 - Load(effective) = 0

Therefore, load = 1.5 + 1.5 + 1.5 + 1.5

     ⇒ Load = 1.5(4)

     ⇒ Load = 6 Volts

Hence, the total voltage of battery is 6 Volts.
