Question

If three 1.5V 2.3Ah batteries are connected in series, the output voltage is_-

3.0 Volts

0.0 Volts

4.5 Volts

1.5 Volts

Answer 1

4.5

Step-by-step explanation:

1.5*3=4.5

Answer 2

4.5V

Step-by-step explanation:

For different batteries connected in series the voltage is given by:

`V_T=V_1+V_2+...+V_n`

for n=3 you have:

`V_T=V_1+V_2+V_3\\\\V_1=V_2=V_3=1.5V\\\\V_T=1.5V+1.5V+1.5V=4.5V`

hence, the output voltage is 4.5V
