Expert Answer:
In both the lighting systems heat dissipated through the resistor is directly proprtional to the brightness produce. Clearly brightness required when we light up a bulb is more than that required when we light up a torch bulb. Hence for greater dissipation of power a 10 W bulb has higher resistance.
