Is there a way to determine the amount of current that can be drawn from a solar panel based on the voltage?
Say you have a 100 Watt solar panel. If you measure 24 volts and then later 20 volts can you say anything about the current being produced?
P = IV but if there is no load...
Thank you all for the replies.
So this is a voltage regulator that can output a larger voltage than is imputed? I plan to use a 5v voltage regulator, 7805, on the other side of the battery to control a microcomputer. I also plan to power this 12v pump...
I'm working on a project where I charge a 12 volt battery with a 12 volt solar panel. Links for the battery and solar panels are below. My question is how I should connect the two. The main thing I can find is that I don't want the solar panel draining the battery. I plan to put a diode from the...
The engineering yield strength, the modulus of elasticity, the original diameter and final diameter of a wire are given. That wire is stretched and it diameter decreases. I am trying to find the engineering strain just before yield and the corresponding true strain.
So I assume I will find...
How do I tell what the coefficient of viscosity is of SAE 10W-30 oil? It is at 25 degrees C. My book says that multigrade oils like this have a non Newtonian blending additive. This doesn't mean I have to treat the substance as non Newtonian does it?
Any help would be appreciated.
so,
{\mathbf{A} \cdot \mathbf{B}} = AB =
\begin{pmatrix}
ae + bg & af + bh \\
ce + dg & cf + dh
\end{pmatrix}
With matrices the dot product means that you need to multiply the matrices? Correct?
What is the difference between matrix multiplication and the dot product of two matrices? Is there a difference?
If,
A =
\begin{pmatrix}
a & b \\
c & d
\end{pmatrix}
and
B =
\begin{pmatrix}
e & f \\
g & h
\end{pmatrix}
then does
{\mathbf{A} \cdot...
so for a one dimensional wave equation the equation is:
{ \partial^2 \psi \over \partial t^2 } = { c^2 \nabla^2 \psi} = c^2 {\partial^2 \psi \over \partial x^2}
Right?
I don't see how I could use separation of variables. If it were something like this:
{ \partial x \over \partial...
So I'm trying to find a solution of the Klein-Gordon equation for a massless particle. I reached the Klein-Gordon from the total energy-momentum equation. Then for a massless particle i get to this equation:
$${ \partial^2 \psi \over \partial t^2 } = c^2 \nabla^2 \psi$$How do I solve for psi? I...
So they use the photoelectric effect right? Does that mean when the camera takes a picture it allows photons of light to interact with a sensor for a certain period of time? How does that create the picture? If i understand it correctly the different photons have different frequencies and their...
In the real world what are power or taylor series used for? Historically were they used for anything? Especially were they used for anything interesting?
Im a little confused about how to calculate threshold energies. The threshold energy is when the energy is as low as it can possibly be and still do what it has to do, yes? So when a neutrino is detected its speed is refracted by water and so it slows down. If at the threshold the neutrino speed...
