Total losses for maximum efficiency will be 4000 watt Bcoz bcoz transformer works at maximum efficiency when it is at 50% loaded so copper loss will become 1000 watt Therefore total loss at maximum efficiency will be 3000+1000=4000
For maximum efficiency Pi=Pcu Iron losses are fixed once transformer is made And the value of Pcu depends on the value of current So only Pcu can be changed Thats why we take Pi=Pcu
@@AnkitMishra-gg2lq yes but transformer works at maximum efficiency when it is 50% loaded means only half load is connected as load is reduced to half copper losses will become 1/4 of 4000 but iron losses are independent of load so it will be 3000 hence total losses at Max efficiency is 1000+3000=4000 w
The correct answer is 4000 W Because condition for maximum efficiency is Copper loss = Iron loss or Variable loss = Fixed loss Then copper losses are variable losses and value of copper losses in question is 4000 w
Sir please CBT 2wlaa season band mat kariye sir usse ham logo ko bahu bahut concept clear hota hai CBT 1 ke liye bhi,,, please please sir PGCIL KO kisi aur time le lijiye Please please please🙏🙏🙏🙏🙏 season CBT. 2 start kar dijiye

lajwab sir
Sir ji Mahendras me ajao ap tecnical ke liye
Sir first question Mai RTU ka full form Remote terminal unit hai Jo SCADA ke lie essential hai. Please check
Thanks sir
Electronic ka bhi sir karwa dijiye sir plz
Okay sure
@@mohitkasanya1266 please sir electronic ka bhi karwa dijiye na
Atul sir se khekr sir electronic pgcil ki bh class krva dijiye plz sir
Remote terminal unit hota h sir
Can u post the pyqs od electronics
Total losses for maximum efficiency will be 4000 watt
Bcoz bcoz transformer works at maximum efficiency when it is at 50% loaded so copper loss will become 1000 watt
Therefore total loss at maximum efficiency will be 3000+1000=4000
Explain properly, I want to know.
For maximum efficiency
Pi=Pcu
Iron losses are fixed once transformer is made
And the value of Pcu depends on the value of current
So only Pcu can be changed
Thats why we take
Pi=Pcu

Sir aap hi badiya se batao itna confuse kyo bolte hai
Losses toh 4000 bhi toh le skte hai 3000 he kyu lenge
Explain ! I want to know
Because iron losses in a transformer are constant
Copper losses are variable
So we cannot take copper losses
Hence,we can take only iron losses
The correct answer is 4000 W
Because condition for maximum efficiency is
Copper loss = Iron loss or
Variable loss = Fixed loss
Then copper losses are variable losses and value of copper losses in question is 4000 w
