Answer

(a) The 100 W bulb is brighter. (b) The power dissipated by the 60 W bulb is 60 W. The power dissipated by the 100 W bulb is 100 W.

Work Step by Step

(a) A bulb's brightness depends on the power that is dissipated. Since the 100 W bulb has more power than the 60 W bulb, the 100 W bulb is brighter. (b) The power dissipated by the 60 W bulb is 60 W. The power dissipated by the 100 W bulb is 100 W.
