    Turn ratio in a step up transformer is 1 : 2, if a Lectanche cell of 1.5 V is connected across the input then the voltage across the output will be:

    A) 0.1 V       

    B)                        1.5V                      

    C)        0.75 V                   

    D)        zero

    Correct Answer: D

    Solution :

                    Key Idea: Leclanche cell gives a DC voltage. A transformer is a device based on the principle of mutual induction, which is used for converting large alternating current at low voltage into small current at high voltage and vice-versa. Transformers are used only on AC and not on DC. Since Leclanche cell gives DC voltage, hence its voltage at secondary output will be zero.
