Welcome to blog help for PHY 122! Here's how it works. For each homework question and lab report we will make a post, this will probably contain a few tips on what the problems are about and how to solve them. If you are stuck on something then instead of emailing us directly you should post a comment in reply to the relevant post. We will try to guide you through tough points and help you understand the problems and the concepts behind them.

I am having a problem with problem 12 part b. They are asking for the energy stored one time constant after the switch is closed. I used the formula W=(1/2)L(I^2) and to find "I," used I=(ε/R)(1-e^(-1/τ)) I plugged "I" into the 1st equation but my answer is incorrect. Where am I going wrong?
Nevermind, I just saw which part I was plugging in wrong. I don't want to give the answer away, but I will say I should not have used t=1s.
