The RC circuit can be modeled using the integral procedure defined earlier. Unlike there, we don’t need to name the procedure we are returning because we don’t need to call it (that is, because the output of the circuit is not used as an input).

(define (RC r c dt)
  (lambda (inputs v0)
    (add-streams (scale-stream inputs r)
                 (integral (scale-stream inputs (/ 1 c)) v0 dt))))
