Hi, most of my thermodynamics class we have been looking up enthalpy on tables when the pressure and temperature is provided. For some homework questions, the values are not on the tables, but fall in between them. What is the correct approach to finding these when the quality is not provided...
Thanks, in an alternate handwritten solution it was written with Cp*1000 which started the confusion. The last couple sentences really summed it up. Unfortunately this class has mostly been taught as a "plug these numbers from the table into these formulas" and a lot of the intuition has been...
Hi there! I have attached an example problem from my thermodynamics textbook, and I understand everything except part (c)
m( h + ke ) = m(c p T + V^2/2)
where Cp is multiplied by 1000 (or ke/1000 as shown in solution.)
why is this part done? I cannot figure it out at all. I see that...
Ah, I do see the error with the reciprocal for Ceq, thank you. So then since both C2 and C3 must have the same voltage, 5.33 V,
Q2/3μF=5.33V
3 μF(5.33 V)=Q
Q2= 15.99 μC
correct?
Taking this farther, I could do the following calculation to see that the charge on the other...
Thank you guys for some of the clarification, my question was mostly assuming negligible resistance due to battery and wire. Mostly, what happens when a silver/copper (or some other wire of low resistance) wire is attached to both ends of the capacitor. Is the discharge so fast it will damage...
Homework Statement
I am trying to determine the charge on C2 which is a 3 μF cap in parallel with a 2 μF cap that are both in series with a 4 μF capacitor. The voltage source is 12V
(diagram attached)
Homework Equations
Q=CV
1/Ceq= (1/C1)+(1/C23)
The Attempt at a Solution...
Disregard that guess about dielectric breakdown, I can see why that wouldn't make sense. I'm grasping for straws here, I just get the idea something is problematic about not including extra resistance.
Hi all,
So I created this account specifically to get some clarification on capacitors. I've been reading alot, but can't seem to find any info on whether a resistor is essential in series to discharge a capacitor. Think of the simplest circuit possible that switches between a battery to...
