I had to do some homeowrk problems and i was hoping someone could just double check my answers... much appreciated.(adsbygoogle = window.adsbygoogle || []).push({});

When you connect a 120 watt bulb and a 60 watt bulb in a parallel circcuit across a standard 120 volt outlet, which is brighter?

the 120 watt bulb is brighter- right? because the current flowing through the circuit connects to both bulbs, and both get the 120 volts but the 120 watt bulb can actually use that amount of power.

If you connect the same bulbs in a series circuit, which bulb is brighter? and why?

The 60 watt bulb is brighter. The current is now divided among the two bulbs and the 60 watt bulb can utilize the entire 60 volts it gets ,while the 120 watt bulb can only light half of it's potential. or does it have to do with the 60 watt bulb being the path of least resistance?
