Enter the battery current (amps) and the battery resistance (ohms) into the calculator to determine the Battery Voltage.
Calculate voltage / current / resistance / power. Enter 2 values to get the other values and press the Calculate button: The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): Example The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): P = V × I Example
The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): Example The power P in watts (W) is equal to the voltage V in volts (V) times the current I in amps (A): P = V × I Example Enter 2 values of magnitude+phase angle to get the other values and press the Calculate button:
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. Vb = Ib * Rb Inserting the values from above into the equation yields: Vb = 105 * 3 = 315 (volts)
