WebJust as with resistance, we can use Ohms Law and rearrage the formula to give us current with I = V / R (Current = Volts / Resistance). So as an example, Volts of 230 divided by a resistance of 23 Ohms gives us (230 / 23) 10 Amps. Rearrange the Power formula to calculate current with I² = P / R (Current Squared = Power / Resistance). WebOhm's Law states that the current through a conductor between two points is directly proportional to the voltage. This is true for many materials, over a wide range of voltages …
