Out of 60 W and 40 W lamps, which one has higher resistance when in use

high wattage of lamp means it will draw more current and less resitance, because operating voltage is fixed as 230 V.
Similarly low wattage means it will draw less current and high resistance.
Hence 40W lamp has high resistance compare to 60W lamp.
