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. | \(2\sqrt{2}~\text{A}\) |
(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. |
