WebInsert the number of Watts (W) and Amps (A) below and click on Calculate to obtain Volts (V). The formula is (W)/ (A) = (V). For example, if you have a power of 10W with a current of 2A the voltage is 10W / 2A = 5V. This comes from the equation V = P / I. Where P is the power in Watts, I is the current in Amps and V is the voltage in Volts. WebFeb 26, 2024 · Using this simple relationship principle, you can calculate the available wattage of any given circuit size: 15-amp 120-volt circuit: 15 amps x 120 volts = 1,800 watts. 20-amp 120-volt circuit: 20 amps x 120 …
Understanding how much power a stepper motor draws
WebFeb 2, 2024 · Find the correct formula, and input the numbers in the correct places: I = P / V = 60 W / 120 V = 0.5 A. Your light bulb needs 0.5 amps of current. Let's look at another example. A resistor has a voltage of 4 volts and a resistance of 8 ohms. WebSo amps are equal to watts divided by power factor times volts. amps = watts / (PF × volts) or. A = W / (PF × V) Example. What is the phase current in amps when the power consumption is 330 watts, the power factor is 0.8 and the RMS voltage supply is 110 volts? I = 330W / (0.8 × 110V) = 3.75A buddy collection 攻略
