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)
Enter the battery current (amps) and the battery resistance (ohms) into the calculator to determine the Battery Voltage. Need help? 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.
So the negative side of the battery is not at ground potential. A batteries negative terminal isn't automatically ground, only if you connect it to ground. Ground is just our reference point, against which we measure voltages. Current is not flowing into or out of it (in this example).
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)
However, if we connect point C to ground and take ground as our negative reference for measuring voltage, then point D is at -3V, relative to point C (=ground). You seem to be confused because of assuming that a negative battery terminal is automatically at ground potential. It's not, only if you connect it to ground.
Notice that the negative side of the battery is not connected to ground directly. So the negative side of the battery is not at ground potential. A batteries negative terminal isn't automatically ground, only if you connect it to ground. Ground is just our reference point, against which we measure voltages.
