(d) The trend in our answers to parts (a), (b) and (c) lead us to expect the smaller the resistance then the smaller to value of t . If we consider what happens to Eq. 30-39 in the extreme case where R 0, we find that the time-derivative of the current becomes equal to the emf divided by the self-inductance, which leads to a linear dependence of current on time: i = ( ε /L ) t . In fact, this is what one have obtained starting from Eq. 30-41 and considering its R 0 limit. Thus, this case seems self-consistent, so we conclude that it
