MHT CET 2022 11th August Evening Shift | Electromagnetic Induction Question 35 | Physics

The magnetic flux through a coil of resistance '$$R$$' changes by an amount '$$\Delta \phi$$' in time '$$\Delta \mathrm{t}$$'. The total quantity of induced electric charge '$$\mathrm{Q}$$' is

$$-\frac{\Delta \phi}{\Delta \mathrm{t}}+\mathrm{R}$$

$$\frac{\Delta \phi}{\Delta \mathrm{t}} \times \mathrm{R}$$

$$\frac{\Delta \phi}{\mathrm{R}}$$

$$\frac{\Delta \phi}{\Delta t}$$

A current 'I' produces a magnetic flux '$$\phi$$' per turn in a coil of '$$n$$' turns. Self inductance of the coil is '$$L$$'. The relation between them is

$$\mathrm{nLI}=\phi$$

$$\frac{\mathrm{nL}}{\mathrm{I}}=\phi$$

$$\frac{\mathrm{LI}}{\mathrm{n}^2}=\phi$$

$$\frac{\mathrm{LI}}{\mathrm{n}}=\phi$$
