Thanks. I can never remember the various SI units for things. I end up sticking to Amp, Volt, etc, and this seems to be the down fall of my understanding. But they just don't stick. Anyway, I know the time was fast, and would play a key part, but not where. Cheers

Homework Statement So this is from a past test put up as a study guide, but I'm stumped here. The question is: A spark jumps between two electrodes, transferring a charge of 5 μC in 2 × 10−3 s. The constant current I that would transfer the same charge in the same time is The Attempt at...

Problem is, that's the homework assignment. Mine is not to question why, ...

Thanks

I guess I would have to say no. Provided the waves are out of phase by the same θ at all times, then they only differ in the θ.

Really, that easy? Do I feel dumb or what? Thanks! Do you know if the wave peak amplitude differences make any difference?

Homework Statement I have a graph of two sinusoids which I need to find the frequency of and phase difference between the two. I have the frequency easily enough, I hope, and I found what I believe is the actual formula for each wave. But I have no clue as to finding the difference. Homework...

Like the heading says, I'm looking for the Uncertainty in the resistor. Since I have never heard this term, Uncertainty, used like we do in physics class I can only presume it means percent error. But I question even that because in our lab we had to perform percent error calculations on our...

Homework Statement I am given a resistor, 40KΩ + or - 20%. I know the uncertainty formula but it involves two variables, but not how to combine these together to get an answer. Not to mention, isn't the uncertainty formula redundant since I know the 20% over or under? Homework Equations...

[a]1. Homework Statement [/b] I have the following circuit attached as PDF and I need to find out if the state of the diode and what V0 is. The forward voltage on the diode is 1V. [a]3. The Attempt at a Solution [/b] I just simply used current division to know that the diode is on since...

Trying to figure how to add on.

Homework Statement C. What is the charge on each of the four capacitors if switch S is closed? I have the charges if the switch is open, C1 and C2 are 8μC and C3 and C4 are 6μC since charges are same on series. Homework Equations The Attempt at a Solution I know to find Ceq and...

Cool thanks.

Homework Statement So I'm given x(t)=4cos(t) and y(t)=sin(t). In a 4 part question, I 1st need to eliminate the parameter to get the equivalent rectangular equation, 2nd I need to find the slope of the tangent to the curve C-y(x) at t=1, 3rd find the times the tangent to the graph is...

Thanks. I got that answer and webassign said it was wrong so I will find out from the professor what the deal is.
