Ask our AI assistant The following formula is used to calculate the Battery Voltage. Variables: To calculate the battery voltage, multiply the battery current by the battery resistance.
Suppose a battery has an internal resistance of 0.3 ohms, and the battery voltage is 0.9V. Calculate the current flowing through the battery. Given: V b (V) = 0.9V, R b (Ω) = 0.3 Ω. Battery voltage, V b (V) = I b (A) * R b (Ω)
The voltage of a battery depends on the internal resistance of the battery and the current flowing through it. The relationship between these parameters is described by Ohm’s law. Battery voltage, V b (V) in volts equals the product of current, I b (A) in amperes and internal resistance, R b (Ω) in ohms. Battery voltage, V b (V) = I b (A) * R b (Ω)
Practical considerations such as the effects of temperature, state of charge and type of circuit protection device are also presented. battery’s short circuit current is typically estimated by dividing its open circuit voltage by its internal resistance.
By discharge testing over a wide range of currents and measuring the battery’s voltage response, its internal resistance can be calculated from the slope of the voltage versus current (R = dV/dI). Extrapolating this line back to zero volts yields the resistance-free or zero voltage short circuit current.
Using Ohm’s law, the potential maximum, zero voltage short circuit current can be calculated by dividing the battery’s nominal open circuit voltage by its resistance (I = V/R).
