Transformer short circuit fault current calculator with equations
Web2 feb. 2024 · Following the Ohm's law formula, we can obtain the amount of electrical power by multiplying the amount of voltage by the current flow through any electrical system. Since we measure voltage in units of volts and current in units of amperes, we can put these together to express power in terms of units of volt-amperes.
