The power dissipated by a resistor:

$\overline{){\mathbf{P}}{\mathbf{=}}{{\mathbf{i}}}^{{\mathbf{2}}}{\mathbf{R}}}$, where **i** is the current through the resistor and **R** is the resistance.

A 60 W lightbulb and a 100 W lightbulb are placed in the circuit shown in (Figure 1). Both bulbs are glowing.

Part A. Which bulb is brighter?

A. The 60 W bulb is brighter.

B. The 100 W bulb is brighter.

C. Both bulbs are equally bright.

Part B. Calculate the power dissipated by the 60 W bulb. Express your answer with the appropriate units.

Part C. Calculate the power dissipated by the 100 W bulb. Express your answer with the appropriate units.
