Power delivered by battery in simple RL circuit

  • #1

Homework Statement


For a simple series LR circuit, find the energy delivered to the circuit by the battery.

Homework Equations


I = (V/R)*(1-e-Rt/L)
P=IV
E=∫Pdt

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:
