Question

Part A Which of the transformers are step-up transformers? Which of thetransformers are step-down transformers? Place the appropriate transformers into the two categories listedbelow.
1st Transformer Vp-240V Np-1000 turns Ns-2000 turns
2nd transformer Vp-120V Np-500 turns Ns-2000 turns
3rd Transfomer Vp-480V Np-2000 turns Ns-1000 turns
4th Transfomer Vp-480V Np-4000 turns Ns-2000 turns
5th Transfomers Vp-240V Np-1000 turns Ns-500 turns

Put them in 2 categories: step down transfomers- and step uptransformers
Vp-120V Np-500 turns Ns-2000 turns
3rd Transfomer Vp-480V Np-2000 turns Ns-1000 turns
4th Transfomer Vp-480V Np-4000 turns Ns-2000 turns
5th Transfomers Vp-240V Np-1000 turns Ns-500 turns

Vp-480V Np-4000 turns Ns-2000 turns
5th Transfomers Vp-240V Np-1000 turns Ns-500 turns

Put them in 2 categories: step down transfomers- and step uptransformers Vp-240V Np-1000 turns Ns-500 turns

Put them in 2 categories: step down transfomers- and step uptransformers

Explanation / Answer

The no of the secondary turns is less than the primarytruns such a transformer is step down and    when the secondary turns are greater than theprimary truns then such a transformer is called step up. step up transformer                                            Vp-240V Np-1000 turns Ns-2000 turns
2nd transformer Vp-120V Np-500 turns Ns-2000 turns step down transformer
3rd Transfomer Vp-480V Np-2000 turns Ns-1000 turns
4th Transfomer Vp-480V Np-4000 turns Ns-2000 turns
5th Transfomers Vp-240V Np-1000 turns Ns-500 turns Vp-120V Np-500 turns Ns-2000 turns step down transformer
3rd Transfomer Vp-480V Np-2000 turns Ns-1000 turns
4th Transfomer Vp-480V Np-4000 turns Ns-2000 turns
5th Transfomers Vp-240V Np-1000 turns Ns-500 turns Vp-480V Np-2000 turns Ns-1000 turns
4th Transfomer Vp-480V Np-4000 turns Ns-2000 turns
Vp-480V Np-4000 turns Ns-2000 turns
5th Transfomers Vp-240V Np-1000 turns Ns-500 turns Vp-240V Np-1000 turns Ns-500 turns
