On topic, or off?

Given this diagram...

If both R1 and R2 are 60W light bulbs, will R2 in Figure 2 light up?

@Tester101 it's a bit GTKY, but if it's kept good subjective it might work

@Tester101 Parenting would likely be a better fit, I think it's OT here since it's not about how to do a project but rather about raising kids. If the question was "what safety procedures should I be following/teaching when letting my child use X power tool?" then I'd say it's on topic.

@Tester101 I VTCed as off topic; too broad or "opinion-based" would work as close reasons too.

@Tester101 In the second revision of your diagram, no -- it's grounded on both sides so how could any current flow through it

@NiallC. I know it's true, but for some reason I just can't understand it.

whats up @Tester101

@lsiunsuex My mind is slowly turning to goo.

YEY!!!!!! so is mine!!!!

gonna spend a few weeks on your side of the fence soon - gonna learn android development haha

@Tester101 let's add the ground invisible wire in.

The middle white line is considered 0 resistance so if you do the resistor math, all the power is going to favor the line as opposed to the resistance. In reality, R2 is using a small amount of power, especially if these lines connecting R1 are long in comparison to R2 but even with the middle line removed they are connected in series.

Maybe it's confusing me so much because I'm not sure how to do the maths, since it's a short-circuited series circuit.

The voltage drop across R1 will be nearly 120V, so if I were to measure from the start of R2 to ground, I'd get almost 0V (or whatever the voltage drop across the neutral wire is in the circuit containing R1)? So the voltage in the circuit containing R2 is almost 0V.

Yeah, 0.something is you even get a reading. It's hard to say a single resistance drops the voltage, if you read between the white/right end of R1 and ground it will be 0V but if you remove the middle wire and read between r1-r2 and ground you'd get 60V (120V circuit). So the voltage drop is relative to the circuit, not on the resistance alone.

Think I've got it sorted now.

Looks good and I didn't have to do the math!

Thanks @Jason

Finally pulling my weight around here :-D

I don't know why that was so difficult for me to understand.

Welcome to Project Update Thursday

This week, I learned how electricity works.

I've been working trim in my kitchen while I wait for the countertop people to return my calls. And I replaced the valves under my bathroom sink when I discovered one of them had been leaking and dripping for a while.

I also learned that some users prefer toasters to lamps, others hate the United States Marine Corps, and yet others are against the equal opportunity employment of lizards.

@BMitch Sounds like it might be time to contact different countertop people.

@Tester101 Unfortunately these guys already have my money, they're reputable enough from what I can tell, they just don't have a clue how to work a phone system.

I learned that if you're using a 1x3 as a straight edge for cutting drywall, be sure that your "helper" gives you back the same 1x3 after he moves everything around while your back is turned:

That's a lot of screws on the ceiling

Looks almost like a habitat project, everyone wants to put a screw in.

If you look between the studs in the first photo, you'll see R38 kraft paper backed insulation. The joist bays aren't 12" deep, so there's a little bit of downward pressure on the drywall

This is a friend's garage; I'm there because I have a drywall hoist. He had some R38 left over from a previous project so wanted to use it up

How much is a hoist to buy? I've always just rented them.

I paid about $150; it was at the low end of the professional price range

A half day rental at just after the half way point in the day gives an all night rental. I can't remember how much it was, but it was darn cheap.

I think this was it: amazon.com/DPH11-Professional-Series-Drywall-Panel/dp/…

But we've had this conversation before...

lol

Some people get all the respect for having a truck to help friends move, others get a drywall lift.

Honestly, this company has the worst phone system, if someone doesn't pickup the VM asks you to enter the extension or lookup the name of the person in the directory, but I have neither an extension or a name so it won't let me leave a message. The VM's I've left before are after the system transfers me to the VA office.

You've tried the usual tricks of pressing 0, random keys, etc?

Hmm, and now the one live person I've reached can't seem to hear me.

Shouting in Russian...

Yup, tried the 0, menu says you should press * to just leave a message, which I do and it repeats the original extension/directory prompt but no longer says to press * for leaving a message.

And now this person's VM cuts the outgoing message off short and beeps while I'm leaving a message. I'm going to get a carrier pidgin.

@BMitch How long has this been going on?

They sound like total cowboys

Left one message on Monday, second on Tuesday, now I'm trying them a bunch today.

I just hope they are better at countertops than they are at phone systems.

Do they have an office nearby you can go yell at someone in person?

not sure how close they are, this is the 3rd party handling the order from Home Depot.

Yell at HD then. They may or may not be able to put pressure on the countertop people, but at least you'll feel better

Woo hoo, they finally called me back, measurement appointment scheduled

Yay!

Seems like harassing individuals instead of any of the main numbers is a better approach.

And now I feel like I've accomplished something for the day, other than installing a bunch of trim. :)

Getting trim work finished is a huge accomplishment IMO

It's fiddly and just takes a bunch of time to get it looking right

@NiallC. That's how I feel about walls. I have a room down to the studs for about 8 months now

@Jason If you're not too far from Portland Oregon, I've been known to rent out my drywall hoist in exchange for pizza'n'beer, barbecue, steak, etc.

There isn't much trim around these cabinets, and the finish nail gun makes it go quick. I will need to caulk a few spots, but it's going to be white walls, white cabinets, and white caulk, so it will all blend together and leave a lot larger margin for error.

What takes me forever is mudding, sanding is miserable, and it takes me a long time to get it smooth and spread out over a large enough area to make the joints unnoticeable. So far, I still notice, but then I also notice all the joints from the original builders.

So what would others do, dab a bit of caulk in the finish nail holes since I'll already have some on my fingers soon, or go buy some new spackle since my current container is almost certainly dried up?

Thanks for joining us for this week's PUT

@NiallC. Gainesville, FL It sounds like a new one is cheaper than gas, but thanks for the offer!
