Battery Voltage Formula
The following formula is used to calculate the Battery Voltage.
Vb = Ib * Rb
Variables:
- Where Vb is the Battery Voltage (volts)
- Ib is the battery current (amps)
- Rb is the battery resistance (ohms)
How to Calculate Battery Voltage?
The following two example problems outline the steps and information needed in order to calculate the Battery Voltage.
Example Problem #1:
- First, determine the battery current (amps). In this example, the battery current (amps) is measured to be 105.
- Next, determine the battery resistance (ohms). For this problem, the battery resistance (ohms) is calculated to be 3.
- Finally, calculate the Battery Voltage using the formula above:
Vb = Ib * Rb
Inserting the values from above into the equation yields:
Vb = 105 * 3 = 315 (volts)
Example Problem #2:
Using the same process as the first example, define the variables outlined by the formula. In this case, these values are:
battery current (amps) = 30
battery resistance (ohms) = 3
Entering these values into the formula or calculator above gives us::
Vb = 30* 3 = 90 (volts)
