WebFeb 13, 2024 · Measure true power P using a wattmeter. Calculate apparent power S by multiplying load voltage V by load current I S = I × V. Find power factor from the formula power factor = P / S. Find the angle cos⁻¹ (power factor) and draw a power triangle. Calculate reactive power Q from Pythagorean theorem: Q = √ (S² - P²). WebResistance calculation from Current and Power: Resistance (R) in ohms is equal to Power (P) in Watts divided by the square of the Current (I) in Amps. hence the formula will be, R = P / I 2. Resistance = Power / Current 2. Ohms = Watts / Amps².
WebTo calculate the resistor needed for a simple LED circuit, simply take the voltage drop away from the source voltage then apply Ohm's Law. In other words... R is the resistance, measured in Ohms (Ω). * The current through the circuit is constant so ILED is also the current through the resistor. This calculator is based on the Ohms Law ...
