Det er klart, at der er en betydelig forskel mellem de forskellige faktorer, der er afgørende for, om der er tale om en bestemt form for kredsløb, og om der er tale om en særlig metode.

Det er ikke muligt at foretage en sådan vurdering, men det er nødvendigt at foretage en vurdering af de faktiske omstændigheder, der gør sig gældende.
