In a 25 KVA, 2000/200 V, Single phase transformer, the iron and full load copper losss are 350 and 400 W respectively. Calculate the efficiency at 0.8 power factor on (i) full load, (ii) half full- load & (iii) ¼ full load.
atā ghaṭabē? 151 (d) Efficiency of 20 kVA, 2500 V/250 V, single phase transformer at upf at rated load and 98% at half rated load. Determine the transformer core loss and full load copper loss. At what load will the maximum efficiency occur?
A 5kw,240v,DC series motor has armature and field resistance are 0.05ohm and 0.02ohm respectively.The iron and friction loss are 800W.Calculate:(I) total copper loss (ii) commercial, mechanical and electrical efficiency (iii) BHP of the motor Please slove this question sir 🙏❤️
Very nice and clean explanation❤
Thank you!
best explanation ever seen on youtube

Nice explained sir.... Thanks a lot. 😇😇 sir please transformer aur moter ke har type ke 1 1 numerical ke 1 short video bnauo..
Thank you sir you are great❤🎉

Please slove this question sir 🙏❤️
Is numerical problem ko next week solve karunga
@@ElectricalTutorial okay sir
Thankx
sir is q ke last me maximum efficiency calculate karte time app x*kva kyun nahi kiye
