We know, Xc=1/2*pi*f*c ------ i Hence, from eqn. i, if f(frequency) increased, Xc gradually decreased. Also we know, Phase angel= tan^-1(Xc/R) So if Xc decreased, also phase angle gradually decreased. |

Any wide description about it. |

Phase angle = arctg ((XL-XC)/R), XL = 0, phase angle = arctg(-XC/R), So tg(alpha) = -XC/R, when XC decrease tg (alpha) from minus go to 0 to be increased. So alpha also from minus go to 0. So the question is how you consider angle increase or decrease. So if alpha from -40 goes to 0 it's decrease or increase? |

Alpha=tan-1(xc/r). xc=k(1/f). Thus xc dec. Alpha dec. |
