Diagram

With the help of a diagram, show how you can use several NAND gates to obtain an OR gate.

**Useful Constants and Relations :**

1. Speed of Light in Vacuum | (c) = 3.00 x 10^{8} m/s |

2. Charge of a proton | (e) = 1.60 x 10^{-19}C |

3. Planck's Constant | (h) = 6.6 x 10^{-34} Js |

4. Permeability of vacuum | (μ_{0}) = 4π x 10^{-7} Hm^{-1} |

5. Electron Volt | (1eV ) = 1.6 x 10 |

6. Unified Atomic Mass Unit | (1u) = 931 MeV |

(π) = 3.14 | |

( ln 2 ) = 0.693 |
