Question
A long time after the switch has been closed on the circuit shown in the figure the energy accumulated in the inductance is 0,110J. What is the value of the resistor R?

HII Calcola la resistenza Nel circuito rappresentato in figura, molto tempo dopo la chiusura dellinterruttore lenergia accumulata nellindut- anza è di 0,110J. ) Qual è il valore della resistenza R? ) Se si vuole che venga immagazzinata più energia nellinduttanza, la resistenza R dovrebbe essere mag- giore o minore rispetto al valore ricavato al punto pre- cedente? Giustifica la risposta. [a) 42 (21 62,0 mH 12 V 7,50 Ω gia in funzione del tempo oni che la resistenza R nel circuito del problema pre- nte sia 14 Ω e che linterruttore sia chiuso allistante
