new question, calc. voltage drop

[MikeMike]

ok, now given flow rate in xC/min and xJ of heat dissapated in xSeconds, how do i find the voltage drop across the circuit?

 

[BlueWeasel]

What is this equation calculating and what are the other variables?

 

[fs5]

spring constant?

oops n/m

Boltzmann constant (k)
1.380 658(12) x 10-23 J/K = 8.617 385(73) x 10-5 eV/K

[Drakkon]

k = constant, pounds of load per inch of deflection
should be given to you in the problem...each sping has its own k value

 

[JoLLyRoGer]

Google?

Or maybe this??

i know its a constant, but whats its value.

this is a biatch

Is that the equation for the force between to charged particles?

yes

I think it's 9 x 10^9. Can't remember what the unit is.

[Mo0o]

k = 9e9 N*m^2/C^2

 

[TheLonelyPhoenix]

k = 1/(4*pi*e0)

Estimates to roughly 9 x 10^9.

Edit: Damn, too slow on the draw.

 

[sic wil]

42.

 

[Heisenberg]

k = 1/(4*pi*epsilon0) where epsilon0 is the permittivity of free space. It is NOT the Boltzmann constant.

Damn. I'm loosing my physics skillz!

winner. actually 8.988 x 10^9

Coulomb's constant. The equation is to determine the force of two electrical charges.

Second semester physics, for me, I think.

Yup, doing it right now.

Fcuk physics :|

 

[MikeMike]

this is for my electrical class. its basically physics.

 

[CombatChuk]

Don't forget k= 1/4*pi*E_0

For your sake (and sanity), I hope that it's not an electromagnetics course.

Man, I hated that ish.

 

[Eli]

God, I wish I was better at math.

 

[MikeMike]

its basic ac/dc circuits.

but now wtf is the formula to figure out voltage when given:

energy used and the amount of electrons moved between two points.

Energy Used (Joules) = Voltage (Volts) * Amount of charge moved (Coulombs)
