1. ## RLC circuit differential equations

So what exactly do I solve for? I assume I go L(-Asin wt) + R(Awcos wt) + (1/C)(Asinwt)=WEo cos wt But what is the variable I attempt to solve for to find the voltage through the capacitor?
2. ## RLC circuit differential equations

Using the values L=50*10^-3, R=100 ohms, C= 1600 microF, peak to peak voltage= 200V, and frequency=100Hz, how do I set up and solve the second order differential equation to find the voltage across the capacitance? I know the equation to use is: L*(d^2i/dt^2)+R(di/dt)+(1/C)i=wVcoswt But I am unsure how to solve it to obtain the voltage across the capacitor Oh, and the intitial conditions are that both the initial voltage across the capacitor and current through the inductor are zero
3. ## Which of the following are reducing sugars?

Beta-D-glucose methyl-alpha-D-glucoside alpha-D-fructose sucrose maltose and also what is the number of the carbon atom that is an aldehyde or ketone group in open chain form?

Thanks for that, will do.
5. ## SN1 and SN2 rections help

What exactly is the difference between SN1 and SN2 reaction mechanisms?

Hi all, I just thought I would comment as I am a newcomer to this forum and say that i think this has to be one of the best forums on the net! I am jealous of the sucess of this forum compared to my own, where I am the only member! haha oh well. I would also like to say, Phi for All, that I believe some new comers (such as some of my friends) are a bit unsure where to start and how to get involved because of the sheer size of the forum and the number of posts that can "drown" you. Just a thought
7. ## The Official "Introduce Yourself" Thread

Hi all, My name is Paul and i am a first year Medical Laboratory Science student at Massey University in New Zealand. I hope to learn a lot from this forum and to share a common science interest with wveryone here.
