___________________________
Known :
Np = 50 turns
Ns = 100 turns
Vp = 25,0 V
Asked :
The voltage across the secondary coil ?
Solution :
Vp/Vs = Np/Ns
25,0/Vs = 50/100
1/Vs = 2/100
2 . Vs = 100
Vs = 50,0 V ✅
2. A transformer has 1000 turns on the primary coil.The voltage applied to the primary coil is 230 V a.c. How many turns are on the secondary coil if the output voltage is 46V a.c.
Jawaban:
Lilitan pada kumparan sekunder berjumlah 200 Lilitan.
Penjelasan:
Diketahui:
[tex]Lilitan\ pada\ kumparan\ primer: N_{p} = 1000\ Lilitan\\Tegangan\ listrik\ pada\ kumparan\ primer: V_{p} =230\ V\\Tegangan\ listrik\ pada\ kumparan\ sekunder:V_{s} =46\ V\\[/tex]
Ditanya:
Lilitan pada kumparan sekunder
Penyelesaian:
[tex]\frac{N_{P} }{N_{S} } = \frac{V_{P} }{V_{S} } \\\frac{1000}{N_{S} } = \frac{230 }{46 } \\N_{S} = \frac{1000}{5}\\N_{S} = 200\ Lilitan[/tex]

6. (1)Water in an electric kettle connected to a 220 V supply took 5 minutes to reach its boiling point.how long would it have taken if the supply voltage had fallen to 200 V ?(2)a voltage of 12 Volts is inserted through the resistor with a resistance of 100 ohm,then how much power is inserted in the resistor?
1)
V = 220 v
t = 5 minutes
time t if V = 200 v ?
Solution
with 220 v supply, required energy
W = P.t = V².t/R
W = 220².5 .60/R joule
with 200 v supply, required energy is not change.
W = P.t = V².t/R
220².5 .60/R = 200².t/R
200².t = 220². 300
t = (220/200)².300
t = 1,21 . 300
t = 363 s
t = 363/60 = 6,05 minutes
2)
V = 12 v
R = 100 ohm
Power ?
Solution
Inserted Power
P = V²/R = 12²/100
P = 1,44 watt

8. 9.0 volts are sent into a transformer with a 10-coil primary loops and a 30-coil secondary loop. The voltage leaving the secondary loop will be
Primary voltage = Vp = 9
Secondary voltage = Vs = x
Primary loop = Np = 10
Secondary loop = Ns = 30
Vp/Vs = Np/Ns
9/x = 10/30
x = 27
9. fisika english tolong bantu yaaa transformer reduces the main voltage from 240 V to 12 V for use in a school laboratory power pack. the current supplied by the power pack is 2 A. what current flows into the power pack? what assumption must you make in this calculation?
Kuat arus yang mengalir pada daya tersebut adalah 0,1 A. Gunakan perbandingan transformator, yaitu:
Vp/Vs = Is/Ip
Penjelasan dengan langkah-langkahDiketahui: Sebuah transformator mengurangi tegangan utama dari 240 V menjadi 12 V untuk digunakan dalam paket daya laboratorium sekolah. Arus yang disuplai oleh power pack adalah 2 A. Ditanya: Berapa arus yang mengalir ke power pack? Jawab:Langkah 1
Gunakan perbandingan transformator, yaitu:
Vp/Vs = Is/Ip
Langkah 2
240/12 = 2/Ip
Ip = 2 (12) / 240
= 0,1 A

11. Why there is a voltage between the two terminals of the secondary coil !
Jawaban:
The two coils are called as primary and secondary coils. In normal use, the input voltage is placed on the primary, and the secondary produces the transformed output voltage. Not only does the iron core trap the magnetic field created by the primary coil, its magnetization increases the field strength.
Penjelasan:
Artinya: Kedua kumparan tersebut disebut kumparan primer dan sekunder. Dalam penggunaan normal, tegangan input ditempatkan pada primer, dan sekunder menghasilkan tegangan output yang diubah. Inti besi tidak hanya menjebak medan magnet yang dibuat oleh kumparan primer, tetapi magnetisasinya juga meningkatkan kekuatan medan.

15. Why transformer coupled class a amplifier has better efficiency than series fed class a amplifier !
Transformer coupled class A amplifier has better efficiency than series fed class A amplifier because of the following advantages:
There is no signal power loss in the base or the collector of the resistors. It can achieve a terrific impedance matching. It has high gain. It provides DC isolation. PembahasanDefinisi dasar dari transformer adalah suatu perangkat yang bisa mengambil tegangan AC pada level tertentu lalu mengubahnya menjadi tegangan lain yang lebih tinggi atau lebih renda di sisi lainnya. Ada dua jenis transformator:
Transformator step up yaitu transformator yang mengubah tegangan di suatu sisi menjadi lebih tinggi di sisi lainnya. Transformator step down yaitu transformator yang mengubah tegangan di suatu sisi menjadi lebih rendah di sisi lainnya.Transformator juga bisa digunakan untuk isolasi sirkuit dari ground yang disebut isolation transformator.
