Kalindi Yadav 7 years, 10 months ago

When a mirror rotates through an angle θ a ray of light reflected from it will rotate through an angle of 2θ. So if a mirror is turned through 15°, the reflected ray will turn through 30°.

Kalindi Yadav 7 years, 10 months ago

Ev Iv is apparent power or virtual power.

1Thank You

Kalindi Yadav 7 years, 10 months ago

Power Factor of an AC circuit is defined as the ratio of true power to apparent power of the circuit. Since,P=Ev Iv cos ϕ Here,P is called true power,Ev Is is called apparent power or virtual power. Thus,Power Factor =True Power/Apparent Power=P/Ev Iv= cos ϕ=R/Z=Resistance/Impedance=R/√R²+(Xl-Xc)²(from Impedance triangle). Power Factor is always positive,but less than one or most equal to one.
