    Calculate the power dissipation of MOSFET (M1) as well as shunt resistance (R5). The condition is the drain of the MOSFET short to Power supply (14V).
    I have attached the circuit diagram as well as MOSFET data sheet.

    You don't have a voltage for V2. Are we to assume that V2 is 0V?

    Assume the mosfet is completely switched on.

    If your mosfet is "completely switched on" the the power dissipation of MOSFET (M1) will be as for any resistor UxI or (IxRon)xI
