Question

the full load copper loss of a transformer is twice its core loss.the efficiency will be maximum at ?​

Answer 1

Answer:

Explanation

Frome sentence

Iron loss =2 copper loss

Equation

Efficiency=Sfull load ×(Pi÷Pc)^½

= 1×(1÷2)^½

=0.0707×100%

=70.7%

Answer 2

Question:

The full load copper loss of a transformer is twice it's core loss.

The efficiency will be maximum at ?​

Concept:

Electricity and magnesitism.

Given : The full load copper loss of a transformer is twice it's core loss.

We have to find:

At which point the efficiency will be maximum?

Answer:

The efficiency will be maximum at 70.7% .

Step by step explanation:

Iron loss is twice. That means copper loss =2

As we know equation of efficiency  is,

Efficiency=S (full load)×(Pi÷Pc)^½

= 1×(1÷2)^½

=0.0707×100%

=70.7%
