(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
