Question

A current passing through a resistor (R = 16 Ω) decreases exponentially with time as I(t) = I0e-αt where I0 = 7.5 A and α = 0.25 s-1.

Calculate the total energy dissipated by the resistor in joules as time goes to infinity. sig.gif?tid=5T88-2F-26-4A-8055-24043
E(t→∞) =

Answer #1

Power = I²R Energy = 8 petat E = (t e=2&tat E= 7.5? Se-zatat 2=0.25 see! E- 56.25 se-oost at L = 0.25 Seat F= 56.25 [e-o-st]
