volt amp = watts?

[tacomafc]

I am second questioning myself here. Is a volt-amp equal to a watt?

 

[Buck Parrish]

Yes, I think it's terminology that's all.

 

[chris kennedy]

There is a true power and apparent power thing here.

Watts=V/A?PF

 

[Jraef]

In a purely resistive circuit, yes. But technically a Watt is V x A x Power Factor, something that occurs in inductive loads such as motors.

Watts=V/A?PF

???

You sure?

 

[Rockyd]

Watt you mean Willis?

 

[cadpoint]

Sometimes its just like work, you need to go get a soda, go fixate on something else and come back to the math ...

Yes V?A?PF

 

[quogueelectric]

Yes V?A?PF

So voltsxCoulombs per/secondxPF???

 

[celtic]

Yes V?A?PF

Was there ever any doubt?

C man is Happy , C man, I don't what to say.

Celtic welcome back, BTW (Busy is Good)

OP I guess it depends on where (what chapter) you learned that W=VA ... I don't what to say.

 

[chris kennedy]

Celtic welcome back

Yes, I second that.

Yes, I second that.

Thanks for the kind words guys

This is the part where you give 480 and myself that dollar, right?

Yes. A "volt" is the same as "one joule per coulomb." An "amp" is the same as "one coulomb per second." When you multiply these two, you are left with "one joule per second." That is a rate of expenditure of energy, and that is the definition of "power."

Here's a buck for each of you:

ohms law. Never needed it til I had to wire HVAC roof top units. Adding electric heat. There was no name plate that said this is the amperes I want.

How would you determine how many lighting outlets you could put on a given circuit?

How would you determine how many receptacle outlets you could put on a given circuit?

dang it man where was I and the 30-06 I need to get a stand by them..wonder how much energy required to drag them to the truck..

I was out a few hours....saw 5 deer standing by the road.
I guess they were waiting for a bus?

I snapped one quick cell shot of a straggler (sorry for the quality...low light, etc)
