   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?
