When I was an apprentice, I was asked a simple question, not having the initiative to acutally hook up this circuit, I just guessed as to what I thought would be correct and was, of course wrong.

I've asked this question of other electricians just to see if anyone knows off hand and very few people acutally get it right. I thought I'd throw it to you guys and see what the responses are.

If you have a 120 volt circuit with a 40 watt and a 60 watt bulb hooked in series, no other loads on this circuit, when you turn the switch on, which bulb will be brighter? And Why?
