Three 85.0-w, 135-V lightbulbs are connected across a Av = 135-V power source, as shown in the figure below. Find the total power delivered to the three bulbs and the potential difference across each. Assume the resistance of each bulb is constant (even though, in reality, the resistance increases markedly with current). R1 AV R2 R3 (a) Find the total power delivered to the three bulbs.
