MHT CET 2021 23th September Morning Shift | Alternating Current Question 153 | Physics

A capacitor of capacity '$$C$$' is charged to a potential '$$V$$'. It is connected in parallel to an inductor of inductance '$$\mathrm{L}$$'. The maximum current that will flow in the circuit is

$$V \sqrt{\frac{L}{C}}$$

$$\mathrm{V} \sqrt{\mathrm{LC}}$$

$$V \sqrt{\frac{C}{L}}$$

$$\frac{\mathrm{VC}^2}{\mathrm{~L}}$$

A step down transformer is used to reduce the main supply from '$$V_1$$' volt to '$$V_2$$' volt. The primary coil draws a current '$$\mathrm{I}_1$$' $$\mathrm{A}$$ and the secondary coil draws '$$\mathrm{I}_2$$' A. $$(\mathrm{I}_1<\mathrm{I}_2)$$. The ratio of input power to output power is

$$\frac{V_1 V_2}{I_1 I_2}$$

$$\frac{V_1 I_1}{V_2 I_2}$$

$$\frac{\mathrm{I}_1 \mathrm{I}_2}{\mathrm{~V}_1 \mathrm{~V}_2}$$

$$\frac{\mathrm{V}_1 \mathrm{I}_2}{\mathrm{~V}_2 \mathrm{I}_1}$$
