What is pi formula? |

What is pi formula? please tell me. |

Akshaya said: (Mar 1, 2014) | |

pi has a constant value = 3.14. |

Sandy said: (Aug 31, 2014) | |

f = (1/2*pie*sqrt(LC)). |

RLC circuit and resonance. |

Anand said: (Jul 21, 2015) | |

At resonance Xc = XL. i.e 4 1/(2*3.14*C*F) = 2*3.14*L*F. F = 1/(2*3.14*sqrt(L*C)). By substituting values we get F = 281 Hz. |

What is the exact formula f = (1/2 * pi * sqrt(LC)) or f = 1/(2 * pi * sqrt(LC)? |

Faiza Malik said: (Dec 8, 2018) | |

Exact formula is calculated as; XL=XC. 2*π*f*L=1/(2*π*f*C). for frequency we can simply it as; 2*π* f^2 *L=1/2*π*C. f=1/2*π*√(L*C). |
