1. The problem statement, all variables and given/known data For a simple series LR circuit, find the energy delivered to the circuit by the battery. 2. Relevant equations I = (V/R)*(1-e-Rt/L) P=IV E=∫Pdt 3. The attempt at a solution Isn't ∫ Pdt = ∫ IVdt = ∫ (V2/R)*(1-e-Rt/L)dt = (V2/R)(t + (L/R)e-Rt/L) ??? The book provides the answer, via a sample problem, of: What am I missing?
