The flux linked with a circuit is given by $\phi=t^{3}+3 t-7$. The graph between tine ( $x$-axis) and induced emf (y-axis) will be a\

Professor PC Thomas Classes · Answer

Given flux $\phi=t^{3}+3 t-7$ Induced emf, $\mathrm{E}=-\frac{\mathrm{d} \phi}{\mathrm{dt}} \Rightarrow \mathrm{E}=-3 \mathrm{t}^{2}-3$\ This is the equation of a parabola but not through the origin\
