WebApr 7, 2024 · Sometimes you will see this formula written as W=A X V. [1] X Research source. For example, if the current is 3 amps (3A) and the voltage is 110V, you multiply 3 by 110, to get 330W (watts). The formula is P=3A X 110V = 330 W (with P standing for … WebThe two wattmeter method, when applied to measure power in a three-phase balanced circuits, provides information that help us to calculate the power factor of the load. Figure 9.47 shows the vector diagram of the circuit shown in Fig. 9.46. Since the load is … Web2. Two wattmeters are connected to measure the input power to a balanced 3-phase load by the two-wattmeter method. If the instrument readings are 8kW and 4kW, ... = 10.62kW Hence wattmeter 1 reads 10.62kW From Equation (1), wattmeter 2 reads (12−10.62)=1.38kW . 4.
