    the question i have is a power supply voltage is 15 volts, and the load current I sub l is at its minumum value, the current through the zener will be __________.

    You can't answer that question because it makes no sense and doesn't contain enough information.

    Think of it this way.

    For a shunt regulator, the current either goes out to the load or down the zener diode.

    To maintain regulation the zener has to at least sink as much current under no load condition as the minimum to maximum load condition will require.
