The current in an inductor when energy is stored. Please help!!! 1. The problem statement, all variables and given/known data What's the current in a 15mH inductor when the stored energy is 42μJ 2. Relevant equations E = 1/2 L i^2 3. The attempt at a solution .000042J = (.5)(.015H)(i^2) .000042J = (.0075)(i^2) .0056 = i^2 √ (.0056) = i .0748331 = i I need to put the answer in with only two sig figs so i put in .07 but it was wrong :grumpy: What am I doing wrong?
