Electrical power formula dc
WebReactive power is given by Q = V I Sinθ which can be positive (+ve) for inductive loads and negative (-ve) for capacitive load.. The unit of Reactive Power is Volt-Ampere reactive i.e. VAR where 1 VAR = 1V x 1A.. In more simple words, in Inductor or Capacitor, how much magnetic or electric field produced by 1A x 1V is known as the unit of Reactive Power. WebPower Factor PF = 0.65. The formula of Electrical Power is P = I x V x PF. P = 3.5 x 12 x 0.65. = 27.3. Therefore, the electrical power consumed in the circuit is 27.3 Watts. Get …

WebApr 13, 2024 · It is good to understand that direct current may differ from a single-phase and three-phase AC system. Suppose you want to convert 3500 watts to amps in different phases of a 120V electrical system with a power factor of 1; the result will be the following: DC – 3500 watts = 29.16 amps. AC Single Phase – 3500 watts = 29.16 amps. WebSep 26, 2024 · Figure 3: Electrical power for a 1500Kv brushless DC motor. Theoretical Approach: To calculate a motor’s electrical power theoretically we use formula 4. To allow us to input values into the formula, we replace ‘mechanical power’ with the right side of formula 2, and ‘heat losses’ with the right side of formula 5, to give formula 6.
