Q3) An umcompensated wattmeter is comected as shown in figure below, to measire the power supplied to the load that consist of a 100 Q resistance in series with an unknown inductance. The wattmeter indicates 126.5 W. and an ammeter and voltmeter measure the load current and voltage as L.11 A and 120 V, respectively with 60 Hz supply frequency. Cakculate (a) The phase angel between the cuITent and voltage. (b) The unknown load inductance valuc Supply V+Vp Load Error /V
