Physics - EMI/AC Question with Solution | TestHub

We know, inducedemf $$\mathrm{e}=-\mathrm{L}\frac{\mathrm{di}}{\mathrm{dt}}$$ During 0 to $\frac{\mathrm{T}}{4},\frac{\mathrm{di}}{\mathrm{dt}}=$ constant $\mathrm{So},\mathrm{e}=-\mathrm{ve}$ For $\frac{T}{4}$ to $\frac{T}{2},\frac{di}{dt}=0$ i.e., $\mathrm{e}=0$ For $\frac{T}{4}$ to $\frac{3\mathrm{T}}{4},\frac{\mathrm{di}}{\mathrm{dt}}=$ constant i.e., $\mathrm{e}=+\mathrm{ve}$
