Q. No.The output of a step-down transformer is measured to be \(24\) V when connected to a \(12\) W light bulb. The value of the peak current is:
| 1. | \(\dfrac{1}{\sqrt{2}}~\text{A}\) | 2. | \(\sqrt{2}~\text{A}\) |
| 3. | \(2~\text{A}\) | 4. | \(2\sqrt{2}~\text{A}\) |

Electrical energy is transmitted over large distances at high alternating voltages. Which of the following statements is (are) correct?
Choose the correct options:
| (a) | For a given power level, there is a lower current. |
| (b) | Lower current implies less power loss. |
| (c) | Transmission lines can be made thinner. |
| (d) | It is easy to reduce the voltage at the receiving end using step-down transformers. |
