    Answer:

    The power transferred to fan is given as P=V

    2

    /R, where R is the total resistance of the circuit. As power is inversely proportional to total resistance. So for maximum power, the total resistance should be minimum. Total resistance here is R=

    6+r

    6r

    +3. r is the variable resistance.

    R is minimum when r=0.

    The device is a resistor.

    • A resistor is a passive electrical device whose main purpose is to regulate the total flow of an electric current.
    • The term fixed resistance refers to a system whose resistance is fixed and cannot be reversed.
    • Such resistances are often used to monitor and restrict current in a known circuit, as well as to provide a consistent amount of heat in heating equipment by using the heating effect of electric current.
