Q. No.An alternating voltage of peak value \(200~\text V\) is applied to the primary \((A'B')\) of the transformer, in the circuit shown in the figure. The diodes \(D_1,D_2\) are ideal, and the transformer is also assumed to be ideal. The frequency is \(50~\text{Hz}.\)
The frequency of the pulsating current through the resistor is
The frequency of the pulsating current through the resistor is
| 1. | \(500~\text{Hz}\) | 2. | \(100~\text{Hz}\) |
| 3. | \(\dfrac{50}{\pi}~\text{Hz}\) | 4. | \(50\sqrt2~\text{Hz}\) |

Match List-I with List-II.
| List-I | List-II | ||
| \(\mathrm{(a)}\) | Rectifier | \(\mathrm{(i)}\) | Used either for stepping up or stepping down the AC voltage. |
| \(\mathrm{(b)}\) | Stabilizer | \(\mathrm{(ii)}\) | Used to convert AC voltage into DC voltage. |
| \(\mathrm{(c)}\) | Transformer | \(\mathrm{(iii)}\) | Used to remove any ripple in the rectified output voltage. |
| \(\mathrm{(d)}\) | Filter | \(\mathrm{(iv)}\) | Used for constant output voltage even when the input voltage or load current changes. |
Choose the correct option from the given ones:
| 1. | \(\mathrm{(a)–(ii), (b)–(iv), (c)–(i), (d)–(iii)}\) |
| 2. | \(\mathrm{(a)–(iii), (b)–(iv), (c)–(i), (d)–(ii)}\) |
| 3. | \(\mathrm{(a)–(ii), (b)–(i), (c)–(iv), (d)–(iii)}\) |
| 4. | \(\mathrm{(a)–(ii), (b)–(i), (c)–(iii), (d)–(iv)}\) |
