1.	In an A.C. circuit I=10 cos(100 t) ampere and `V=20 sin(100t). The power loss in the circuit will beA. 20 wattB. 200 wattC. 0 wattD. 50 watt
Answer» Correct Answer - C `I = 10 cos (100 t) = 10 sin (100t+(pi)/2)` There is a phase diff. Of `(pi)/2` between I and V. `:.` Power factor = `cos theta =0 :.` Power less =0.
