प्रश्न
Differentiate step up and step down transformer.
Advertisements
उत्तर
| Sr. No. | Step up transformer | Step down transformer |
| 1. | The transformer used to change a low alternative voltage to a high alternating voltage is called a step up transformer, i.e. (Vs>Vp). | The transformer used to change a high alternating voltage to a low alternating voltage is called a step down transformer (Vs <Vp). |
| 2. | In a step up transformer, the number of turns in the secondary coil is more than the number of turns in the primary coil (Ns > Np) | In a step down transformer, the number of turns in the secondary coils are less than the number of turns in the primary coil (Ns < Np) |
