Jadi nilai hambatan resistor = 46x 104 5% ohm atau 460.000 5% ohm atau 460K 5% ohm
2. Terdapat resistor 6 Warna dengan gelang/pita warna berurutan Coklat, Hitam, Hijau, Hijau, Perak dan Merah, Berapakah nilai hambatan (resistansi) resistor tersebut?
Diketahui :
Sebuah Resistor 6 gelang memiliki pita warna Coklat, Hitam, Hijau, Hijau, Perak dan Merah.
Ditanya :
Berapakah nilai hambatan resistor?
Jawab :
a. Karena diketahui Resistor merupakan jenis 6 warna, kita tampilkan dulu tabel resistor 6 warna .
| Kode warna | Pita 1 | Pita 2 | Pita 3 | Pita 4 | Pita 5 | Pita 6 |
| Hitam | 0 | 0 | 0 | 10° | ||
| Coklat | 1 | 1 | 1 | 10¹ | 1% | 100 ppm |
| Merah | 2 | 2 | 2 | 10² | 2% | 50 ppm |
| Oranye | 3 | 3 | 3 | 10³ | 15 ppm | |
| Kuning | 4 | 4 | 4 | 10⁴ | 25 ppm | |
| Hijau | 5 | 5 | 5 | 105 | 0,5% | |
| Biru | 6 | 6 | 6 | 106 | 0,25% | |
| Ungu | 7 | 7 | 7 | 107 | 0,1% | |
| Abu-abu | 8 | 8 | 8 | 108 | ||
| Putih | 9 | 9 | 9 | 109 | ||
| Emas | 0.1 | 5% | ||||
| Perak | 0.01 | 10% |
b. Selanjutnya kita tampilkan nilai (angka) dari masing masing gelang warna.
Gelang ke-1 : Coklat = 1
Gelang ke-2 : Hitam = 0
Gelang ke-3 : Hijau = 5
Gelang ke-4 : Hijau = 5 maka 105
Gelang ke-5 : Perak = Toleransi 10%
Gelang ke-6 : Merah = Koefisien suhu 100 ppm/oC
c. Setelah itu kita lakukan tahap menghitung warna resistor tersebut.
Jadi nilai hambatan resistor = 105 * 105 = 10.500.000 Ohm atau 10,5 MOhm dengan batas toleransi kurang lebih 10% dan koefisien suhu sebesar 100 ppm/o.

We’re a bunch of volunteers and opening a new scheme in our community.
Your web site offered us with valuable info to work on. You have done an impressive
process and our entire community will probably be thankful to you.
Greetings I am so excited I found your blog,
I really found you by mistake, while I was searching on Digg for
something else, Nonetheless I am here now and would just like
to say thanks for a fantastic post and a all round
enjoyable blog (I also love the theme/design),
I don’t have time to look over it all at
the moment but I have saved it and also included your RSS feeds,
so when I have time I will be back to read much more, Please do keep
up the superb jo.
I’m not sure where you’re getting your information, but great topic.
I needs to spend some time learning more or understanding more.
Thanks for magnificent information I was looking for this info for my mission.
wonderful issues altogether, you just won a brand new reader.
Ulasan yang singkat dan jela, sangat membantu dalam menyelesaikan tugas kuliah saya.Thanks kak
Semangat terus update content nya kak azka….Btw, thanks sudah dituliskan tutorialnya perihal kode warna resistor ini
I am really impressed with your writing skills as well as
with the layout on your blog. Is this a paid theme or did you modify it yourself?
Either way keep up the excellent quality writing, it is rare to see a great
blog like this one these days.
I’m impressed, I have to admit. Seldom do I encounter a
blog that’s equally educative and amusing, and without a doubt, you’ve hit the nail on the head.
The issue is something too few folks are speaking intelligently about.
I’m very happy that I came across this in my search for something relating to this.
Ternyata selama ini ada yg kurang benar cara ngitung saya. Thx ya kak pencerahannya.sangat membantu sekali
Good site you have got here.. It’s difficult to find high-quality writing like yours nowadays.
I seriously appreciate individuals like you! Take
care!!
