In the first method the heater with 1500Watts connect, i.e large load is connected in first of a sequence so most power consumed by this. The 100 & 40 watts bulb will illuminated lighter.
In the second method, the 40 watts is connected as first in a sequence and the 1500 watts and 100 watts, so the 40 watts bulb will illuminate higher.
