Find the correct formula, and input the numbers in the correct places: I = P / V = 60 W / V = A. Your light bulb needs amps of current. Let's look at another example. A resistor has a voltage of 4 volts and a resistance of 8 ohms. How to find watts? You need to combine both Ohm's and Watt. 7 The Watt’s Law formula is all that’s needed for this conversion. The wattage (power produced) is calculated by multiplying the amps (current) by the voltage To convert amps (electrical current) to watts (electrical power) at a fixed voltage, you can use the equation: watts = amps × volts. Simply multiply your amps figure by the voltage. 8 Kalkulator for watt (W) / volt (V) / ampere (A) / ohm (Ω). 9 Elektrisk strøm i ampere (A) til elektrisk kraft i watt (W) kalkulator. 10 Amps calculations The current I in amps (A) is equal to the voltage V in volts (V) divided by the resistance R in ohms (Ω): The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V): The current I in amps (A) is equal to the square root of the power P in watts (W) divided by the resistance R in ohms (Ω). 11 I (A) = P (W) / (√ 3 × PF × V L-L (V)) Effektfaktoren for resistiv impedansbelastning er lig med 1. Beregning med linje til neutral spænding Fasestrømmen I i ampere (A) er lig med effekten P i watt (W) divideret med 3 gange effektfaktoren PF gange linjen til neutral RMS-spænding V L-N i volt (V): I (A) = P (W) / (3 × PF × V L-N (V)). 12
