Extracted text: In an Industry, three phase power measurement is carried out, using two wattmeter method, each wattmeter reads 10 kW, when the pf is unity. What does each wattmeter reads when the pf falls to (i) 0.6 lag and (ii) 0.573 lag. The total three-phase power remains unchanged. (i) W1 at 0.6 lag (i) W2 at 0.6 lag (ii) W1 at 0.573 lag (ii) W2 at 0.573 lag
