The potential difference across the inductor is e=E-iR Hence the plot of e versus i is a straight line with negative slope. <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-lrrr0vfc9hlnmf7k.jpg" />

Q. A battery of e.m.f. E is connected with series L−R circuit as shown in circuit. At t=0 switch S is closed, If e denotes the induced e.m.f. across the inductor and i the current in the circuit at any time t , then which of the following graphs shows the variation of e with i ?

The potential difference across the inductor is e=E−iR Hence the plot of e versus i is a straight line with negative slope.

The potential difference across the inductor is $e = E - i R$
Hence the plot of e versus i is a straight line with negative slope.
