Phase angle = tan-1(Xc/R), So Xc must be greater than R. |

Capacitor inject the reactive power. |

For pure capacitor angle = 90. If R increases then angle decreased. So increases angle R decreased. |

Phase angle tan-1(Xc/r). Given 45 degrees. Xc/R = tan-1 45. So Xc = R. |

@Hareesh, What you said is right. But the question is to mention the condition for phase angle above 45 degrees so Xc>R. |

It is not tan-1. It is tan inverse. |

For pure capacitor angle = 90. If R increases then angle decreased. So increases angle R decreased. So, I agree with the given answer. |
