Ohm Law Calculator!

Ohms Law calculators for current, voltage, resistance, and power. You may key in two of the four factors in Ohms Law. The various possible formulas for Ohms law are as follows:P = power in wattsE = voltage in voltsI = current in ampsR = resistance in ohmsP = E2 / RP = I2 * RP = E * IE = sqrt(P * R)E = P / IE = I * RI = E / RI = P / EI = sqrt(P / R)R = E / IR = E2 / PR = P / I2
