Hi there.
I'm trying to evaluate the energy dissipated due to Joule effect on a resistor within an RC circuit
(R, C, and battery in series), with the capacitor initially uncharged.
Till now I just came up with the formula for the current flowing in the circuit
[itex]i(t) = e^{-\frac{t}{RC}}[/itex], resulting from a differential equation.
The energy dissipated by the resistance should be the power over R integrated from 0 to ∞:
[itex]\displaystyle E = \int_0^\infty P(t)dt = \int_0^\infty e^{-\frac{t^2}{(RC)^2}}dt[/itex]
which appears to be something I just can't calculate.
I'm quite sure there's a simpler way to do this.. do yo have any hint?
