1.Pada sebuah transformator terdapat jumlah kumparan primer 1200 lilitan. Jika Tegangan Primernya 220 V, Tegangan Sekundernya 44

V, Berapakah Jumlah lilitan Sekundernya ?
2.Sebuah Trafo memiliki Daya Primer (Pp) 50 Watt . Jika Tegangan Sekunder (Vs) yang dihasilkan 100 volt dan Arus Sekunder (Is) 0,4 Ampere . Tentukan Efisiensi Trafo tersebut !

3. Sebuah trafo Tegangan Primer (Vp) = 100 volt dan Tegangan Sekunder (Vs) yang dihasilkan 50 volt , dan kuat Arus sekunder ( Is) = 0,4 A. Maka besar kuat arus primer adalah … Termasuk jenis trafo apakah soal ini ?​

Drag each tile to the correct location on the table. Each tile can be used more than once, but not all tiles will be used. Lewis
son4ous [18]

The fill up for the 3rd  step is y - 250 =  340x.

  • The fill up of the 5th step is x = \frac{y-250}{340}
  • The fill up of the 6th step  is \frac{8750-250}{340} = 25 = x, \frac{8750-250}{340}= 34 = x
  • The justification for the 2nd step is subtraction PE.
  • The justification for the 4th step is division PE.

<h3>What is the simplification  about?</h3>

Note that:

y-250 = 250 + 340 x - 250

y = 250 + 340x.

Make x the subject of the formula:

y - 250 =  340x.

then y-250/340 = x

Then  x = \frac{y-250}{340}

The justification for the second step is subtraction property of equality because it undergoes subtraction and the collection of like terms and then subtracting them from one another as shown below:

y-250 = 250 + 340 x - 250

y= 250 + 340x - 250 + 250

Note that (-250 + 250) = 0

y = 250 + 340x.

Lastly, The fill up of the 6th step is substitution of the amount of money  saved and  then simplifying it.
