Formula to determine watts
WebFeb 2, 2024 · We calculate reactive power for a three-phase circuit as the power due to the sine component of the phase current, i.e., the product of apparent power (S) and the sine of the phase angle: Q = S × sin φ; So, in terms of phase quantities, reactive power is: Q = 3 × V Ph × I Ph × sin φ; And in terms of line quantities, the reactive power ... WebJan 29, 2024 · Electric current, represented by I, which is measured in amps (A), can be found by dividing power in watts (W) by the volts (V) of voltage. This is represented by the following formula: I (A) = P (W) / V (V) [4] Or, …

WebFeb 2, 2024 · FAQ. This kVA calculator will help you determine the apparent power over a particular operating voltage and current. Similarly, it also works as volts and amps to kVA calculator. As an added feature, this tool can also function as a kVA to kW calculator to help you easily convert kVA to kW or kVA to watts. In this tool, you will learn what kVA ... WebThe 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 …
WebYou can calculate amps from watts and volts. You can't convert watts to amps since watts and amps units do not measure the same quantity. DC watts to amps; AC single phase watts to amps; AC three phase watts to amps; DC watts to amps calculation formula. The current I in amps (A) is equal to the power P in watts (W), divided by the … WebWatt is the unit of power (symbol: W). The watt unit is named after James Watt, the inventor of the steam engine. One watt is defined as the energy consumption rate of one joule per second. 1W = 1J / 1s. One watt is also defined as the current flow of one ampere with voltage of one volt. 1W = 1V × 1A.
WebYou can calculate watt-hour from watts and hours, but you can't convert watts to watt-hour, since watts and watt-hour units represent different quantities. Watts to watt-hour calculation formula. The energy E in watt-hour (Wh) is equal to the power P in watts (W), times the time period t in hours (h): E (Wh) = P (W) × t (h) So. watt-hour ...
