    In a step up transformer, the turns ratio of primary and secondary is\[1:4\]. A leclanche cell of emf 1.5 V is connected across the primary. The voltage developed across the secondary will be

    A)  3 V                                        

    B)  6 V

    C)  1V                                         

    D)  zero

    Correct Answer: B

    Solution :

                    NAND gate is the inversion of AND gate i.e.      \[AND+NOT=NAND\] So, the truth table for NAND gate is
