CUET Preparation Today
When magnetic flux through a coil is changed, the variation of induced current in the coil with time is as shown in graph. If resistance of coil is 10 W, then the total change in flux of coil will be |
4 Wb 8 Wb 2 Wb 6 Wb |
2 Wb |
$ \text{Change in flux } \Delta \phi = E.\Delta t = RI\Delta t = 10 \times \frac{1}{2} \times 4 \times 0.1 = 2Wb$ |
