The voltage produced by the first battery is 0.32 volt greater when compared to the voltage produced by the second battery

Data obtained from the question

From the question given above, the following data were obtained:

  • Voltage produced by the first battery = 3.12 volts
  • Voltage produced by the second battery = 2.8 volts
  • How great is the voltage of first =?

How to determine how great the voltage of the first battery is

We can obtain how great the voltage of the first battery is compared to the voltage if the second battery as follow:

How great is the voltage of first = Volatge of first - voltage of second

How great is the voltage of first = 3.12 - 2.8

How great is the voltage of first = 0.32 volt

Thus, the voltage of the first battery is greater than the voltage of the second battery by 0.32 volt
