Circuit Problem with Wattages instead of Resistances

[aznshark4]

Homework Statement

there is a 110-V battery serving as a voltage source, and the circuit goes like:

from the battery, there is a 100-Watt bulb connected, then the circuit branches into two parallel wires each with 100-Watt bulbs, then the wires rejoin and lead back to the battery, find everything you can.

Homework Equations

P=VI
R=V/I

The Attempt at a Solution

I don't even know where to begin, I tried finding the current but realized that I needed the Power too to solve, and I don't know how to get the power either.

Imagine a single 100W bulb connected directly to 110V battery. Can you calculate current?

Try to figure out the effective resistance of the circuit first.

Try to figure out the effective resistance of the circuit first.

it's 3R/2 but i still don't know R

 

[NeoDevin]

it's 3R/2 but i still don't know R

Consider a single light bulb on a simple circuit. That's what the 100W power rating is (generally) defined for.
