    An experiment is performed to determine the \[1-V\]characteristics of a Zener diode, which has a protective resistance of \[R=100\,\Omega ,\] and a maximum power of dissipation rating of \[1W\]. The minimum voltage range of the DC source in the circuit is:

    A)  \[0-5\,V\]

    B)  \[0-24\,V\]

    C)  \[0-12\,V\]

    D)  \[0-8\,V\]

    Correct Answer: C

    Solution :

    [c] The minimum voltage range of DC source is given by \[{{V}^{2}}=PR\,\,\,\,\,\,\,\,\because \,\,\,P=1\,watt,\] \[R=100\Omega =1\times 100\] \[\therefore \,\,\,\,\,\,\,\,V=10\,\,volt.\]
